Question

What is the equation in point-slope form of the line passing through (2, 2) and (4, 8)?

(y - 2) = 3(x - 2)

(y + 2) = 3(x + 2)

(y - 8) = -3(x - 4)

(y + 8) = -3(x + 4)

Answer 1

its the first one @andy11

Answer 2

plug in y-y1 = m(x-x1) ;
m = (y2-y1)/(x2-x1)

Answer 3

you sure?

Answer 4

yup i am @andy11 100% sure

Answer 5

ok thank you! do you think you can you help with 1 more ?
