what is the equation of a line with point A (0,-2) and point B(-3,2)?

Question

1. y=3/6x+4
2. y=-3/7x-2
3. y=-4/3x-2
4. y=4/5x+5

Answer 1

AB has slope = -4/3 = (-2-2)/0--3) only choice 3 has slope -4/3

y=(-4/3)x + b, plug in (0,-2) to solve for b = y intercept

-2 = (-4/3)(0) = b, b=-2

y=-4x/3 -2 or y=(-4/3)x -2

3 is correct
