Question

Write the equation in slope-intercept form with the point (2,7.5) with an x intercept of −1. And plz tell me how you got it Thanks!

Answer 1

First you must find slope using two points (2,7.5) and (-1,0).
0-7.5 = -7.5
-1-2 = -3
-7.5/-3 = 2.5
y - 0 = 2.5 ( x + 1)
y - 0 = 2.5x + 2.5
y = 2.5x + 2.5
$y = 2.5x + 2.5$
