Question

Line AB goes through the points A (0, –4) and B (6, 2). Which equation represents line AB?

Answer 1

y + 4 = x

Explanation:

Answer 2

y=mx+b
m=slope
b=yintercept

slope=(y2-y1)/(x2-x1) where you have the points
(x1,y1) and (x2,y2)

(0,-4) and (6,2)
slope=(2-(-4))/(6-0)=6/6=1
y=1x+b
sub a point
(0,-4)
(x,y)
-4=1(0)+b
-4=0+b
-4=b
y=x-4 is the equation of line AB
