Question

Find the equation in standard form which passes through (-2,-7) and (1,-1). You must show all your work.

Answer 1

m=(y2-y1)/(x2-x1) to find slope

then plug things in (y-y1)=m(x-x1)

Answer 2

would the answer be 2x - y = -3?

Answer 3

check your signs pls

Answer 4

would it be -2x - y =-3..?

Answer 5

m=(-1+7)/(1+2)=6/3=2

y+1=2(x-1)
y+1=2x-2
y=2x-3
-2x+y=-3
