Question

EXAM TOMORROW PLEASE HELP Find equation for the line that passes through (-5, 12) with a x-intercept of -8 I know how to find slope, but how do i find b in y=mx+b??

Answer 1

what is your slope going to be?

Answer 2

4

Answer 3

you put it in point slope form (thats the easiest way to do it)

Answer 4

y - y1 = m(x - x1)

Answer 5

y - 12 = 4(x + 5)
y - 12 = 4x + 20
y = 4x + 32

Answer 6

(y = mx + b)

Answer 7

your y-intercept is (0, 32)

Answer 8

thank you!
