Question

Graph the following equationy=3x-4

Answer 1

Since a single line passes through two points, then you can take two values of x and replace them in the given equation to obtain their corresponding values in y. Then you graph the points found and join them.

So for example, if you take the values of x, x = 2, and x = -3, you have

`\begin{gathered} x=2 \\ y=3x-4​ \\ y=3(2)-4​ \\ y=6-2 \\ y=-2 \\ \text{ Then you have the point} \\ (2,-2) \end{gathered}`
`\begin{gathered} x=-3 \\ y=3x-4​ \\ y=3(-3)-4​ \\ y=-9-4 \\ y=-13 \\ \text{ Then you have the point} \\ (-3,-13) \end{gathered}`
