Question

Given a point and the slope, write an equation of the line in point-slope form.

m = -4/5
(-4, 9)

how do you solve this?

Answer 1

point slope form =
y=mx+b

Answer 2

there's a shortcut,
use:

y - y1 = m(x-x1)\[ y - 9 = -\frac45(x-(-4)) \]

Answer 3

y-9=-4/5(x+4) this is the answer i got

Answer 4

Now solve this for y

Answer 5

having trouble. :/
