Question

What is the equation in point-slope form of the line passing through (–2, 0) and (2, 8)?

Answer 1

first you need to determine the slope

so use the slope formula

m = (y2 - y1)/(x2 - x1)

Answer 2

tell me what you get

Answer 3

i got 2

Answer 4

correct

Answer 5

now use the point slope form

y-y1 = m(x-x1)

Answer 6

so far i got y-0=2x-4

Answer 7

you keep it in point slope form

Answer 8

so don't distribute

Answer 9

so y-0=2(x-{-2})

Answer 10

I got it! thanks.

Answer 11

good, you can simplify things to get

y-0 = 2(x+2)
