Question

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

Answer 1

First you need the slope: (y2-y1)/(x2-x1) => (8-0)/2-(-2)) = 8/4 = 2

Answer 2

now we have the slope, the equation is:
y = mx + b where m is the slope and b is the intercept
using the slope and a point we have:
0 = 2(-2) + b
0 = -4 + b
4 = b
so the equation is y = 2x + 4

Answer 3

y = 2(x + 2)

y = –2(x + 2)

y = 2(x – 2)

y = –2(x – 2)

Answer 4

those are the answers given

Answer 5

that's the same as y=2(x+2) (just factored the 2 out)

Answer 6

ok i got it lol sorry had a dumb moment thanks tbates
