Question

How do you graph `y=2x+1` using intercepts?

Answer 1

The intercepts of the graph will be (0, ?) and (?,0).

Explanation:

First, let y = 0 and solve for x: `0 = 2x + 1` so `-1 = 2x`
therefore `-1/2=x`. Your x-intercept is (`-1/2,0`).

Find the y-intercept by substituting x = 0: `y = 2*0 + 1`
so y = 1. Your y-intercept will be (0,1).

Plot these points and make your graph: (see below)
