Question

How do you graph `y=7x+3` by plotting points?

Answer 1

Refer to the Explanation.

Explanation:

`y=7x+3` is a linear equation in slope-intercept form, `y=mx+b`, where `m` is the slope and `b` is the y-intercept.

Since it's a linear equation, you only need two points.

Points
`x=0,` `y=3`
`x=-1,` `y=-4`

Plot the points on the graph and draw a straight line through the points.
