Question

i know this problem was done but im still confused. Find the equation of a line passing through (-2,3) (-1/2,6)

Answer 1

i understand first you find slope... then what? please help!!

Answer 2

Do you the y = mx + b formula?

Answer 3

yes

Answer 4

Yeah, so when you find the slope, you can put that in for m.
Since you already know two points, you can pick one of them, for example -2,3 into the equation.
So you get 3 = -2x (what you got for m) + b
then you just solve for b

Answer 5

x is multiplication*

Answer 6

so y=2x+7 would be the final answer?

Answer 7

yes

Answer 8

thank you!
