Question

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

Answer 1

First Find Slope

Answer 2

\[\tfrac{y2-y1}{x2-x1}\]

Answer 3

what's that^

Answer 4

barely see that^

Answer 5

then... use....\[y-y1 = m(x-x1)\]

Answer 6

hold on lemme plug the numbers in.......

Answer 7

find slope

m = \[\frac{ y1-y2 }{ x1-x2 }\]

Answer 8

-2 - 2^1 = m(0-8^1)

Answer 9

use any of the point now and find b in the below equation

y=mx+b

Answer 10

for (-2,0) and (2,8)

m = (8-0)/(2-(-2)) = 8/4 = 2

now consider point(-2,0)

we have y=mx+b
hence we get

-2 =2*0+b
therefore b=-2

then equation in point form is y=2x-2
