Linear means straight, and a graph is a diagram showing a connection or relation between two or more quantities.

Hence, a linear graph is nothing but a straight line drawn on a plane connecting the points on x and y coordinates.

[{"selector":"#anim-24f7b72b-6baf-49db-b586-b6968b68b63f","keyframes":{"transform":["translate3d(-115.18988%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-dda4afbe-ba49-48d1-ace9-b961550502e0","keyframes":{"opacity":[0,1]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-5d745b51-d7aa-48a2-b546-483bb603067d","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

We use linear relations in our everyday life, and by graphing those relations in a plane, we get a straight line.

[{"selector":"#anim-3ddda0c9-849a-4219-a514-cc8d3cdba92b","keyframes":{"opacity":[0,1]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-fa9a3365-7a53-45c7-a2bb-8271b7a5fb29","keyframes":{"transform":["translate3d(0px, -167.04981%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Now that you have an introduction to the linear graph let us explain it more through an equation. y=mx+c

[{"selector":"#anim-cc97aea8-c8fd-4be8-baeb-3bef7cf7f89d","keyframes":{"opacity":[0,1]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-d8e688a1-129c-4077-a1fb-38613e6d4fb8","keyframes":{"transform":["translate3d(115.18987%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

The gradient between any two points (x1, y1) and (x2, y2) are on the linear or straight line.

[{"selector":"#anim-4d82114a-52c2-4a8e-ae50-8080a6b47b7d","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-bb0bb13b-8a0b-4319-a014-7914cd1cdf15","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

The value of gradient ‘m’: Is the ratio of the difference of y-coordinates to the difference of x-coordinates.

[{"selector":"#anim-2c579e73-f3bb-4ef9-9a5b-fa3e86ee775d","keyframes":{"transform":["translate3d(-115.18988%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-4dced681-b47d-4255-8ad9-6e75f21204b2","keyframes":{"opacity":[0,1]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3b8c2724-fd77-4890-b556-ea6355be77c5","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

The linear equation can also be written as,

[{"selector":"#anim-921c9a8b-c1ba-457d-9a6a-4643b4e905b7","keyframes":{"transform":["translate3d(-115.18988%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-14db8345-6a3c-423f-889a-7b88b9e10da3","keyframes":{"opacity":[0,1]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ad001d38-1c39-4785-af4d-680dd8aea1d4","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Let's look at a few examples of linear graph definitions.

[{"selector":"#anim-65557377-77f7-4d4c-b4ba-59b3a3a90493","keyframes":[{"offset":0,"transform":"translate3d(0, -319.41637%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.29,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.45,"transform":"translate3d(0, -89.819883244%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.61,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.71,"transform":"translate3d(0, -30.536204972%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.8,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.85,"transform":"translate3d(0, -11.467047682999999%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.92,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.96,"transform":"translate3d(0, -4.982895372%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":1,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"}],"delay":0,"duration":1600,"fill":"both"}] [{"selector":"#anim-aba9a7b9-0dc5-47b8-a996-58a0784e2732","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-c7de5ace-fd10-4c41-89fe-06487e40fb08","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

Let's assume that y=2x+1 is a straight line. First, we must construct the table below to determine the x and y coordinates.

[{"selector":"#anim-c25831a4-2c4b-4a4e-b744-ec5383db4131","keyframes":{"opacity":[1,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-f4ce16a3-2d99-45bf-be0d-51e77111e9f7","keyframes":{"transform":["scale(3)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

By using above coordinates we can plot a graph which forms a linear line.

[{"selector":"#anim-0b73116c-78cd-40c5-ab5c-79167d93ceed","keyframes":{"transform":["translate3d(-114.87342%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-09d066e1-1853-4470-ac29-e7d001709369","keyframes":{"opacity":[0,1]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-37c21d3b-554e-47e9-bc85-11c988e5a51e","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":1500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Graph of y = 2x + 1

[{"selector":"#anim-3160650c-f243-4364-92a2-5d1ff9345e8f","keyframes":{"opacity":[1,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-678f1b55-5ba5-4b41-8bee-c205754f80f1","keyframes":{"transform":["scale(3)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] [{"selector":"#anim-cda8a15e-1b85-40de-bc6e-4198df64e0f4","keyframes":{"opacity":[1,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-85b166bb-c66d-4682-a682-c3eaf82dff61","keyframes":{"transform":["scale(3)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

Hope you understood how to draw a linear graph.
