Answer:
Choice C y = -3x - 4
Explanation:
slope is negative (line slants down), so you can toss out answer D.
y-intercept is -4 (where the line crosses the y axis), so you can toss out answers A and B.
That leaves C as the right answer.
Just to prove that the slope = -3, calculate it:
y = (-4-2) / (0--2) = -6/2 = -3
