Question 52572: In class we are working on reviewing writing linear equations. i know how to solve or write an equation when i have a slope and a point, and i also know how to solve when i have two points. My teacher however forgot to give us notes on how to solve when they give us an x-intercept and a y-intercept. For example:
x-intercept=3, y-intercept=2.
Could you please help me?

You can put this solution on YOUR website!
x-intercept = 3 ~> (3,0)
y-intercept = 2 ~> (0,2)
m = (y2 - y1)/(x2 - x1) = (0 - 2)/(3 - 0) = -2/3
y - y1 = m(x - x1)
y - 2 = (-2/3)(x - 0)
y - 2 = -2x/3
y = -2x/3 + 2
