Question

What is the equation of the line with an x-intercept of -2 and a y-intercept of 1?

Answer 1

the desired line is y = (1/2)x + 1

Explanation:

Write these two points as (0, 1) and (-2, 0).

Now, as we go from (-2, 0) to (0, 1), x increases by 2 and y increases by 1. Thus, the slope, m, of the desired line is m = rise / run = 1 / 2.

Then the desired line is y = (1/2)x + 1 (since b is already given as (0, 1) )
