What is the equation of a line that passes through points (0, 4) and (-4, -8)?

Ay = 2x + 4
By = 2x - 4
Cy = 3x + 4
Dy = 3x - 4

slope = (-8 - 4)/(-4 -0) = -12/-4 = 3

y-intercept so b = 4

equation: y = 3x + 4

answer: C. y = 3x + 4

the answer is D. you know that the equation must end in +4 as the yintercept is at four (y=4 when x=0)
then you can work out that it is 3x because when x changes by -4, y changes by -12, which is three times as much.
Hope this makes sense!
