Question

Which of the following has a slope of -3 and a y-intercept of -4 ?

(A) y = -3x + 4
(B) y = 3x + 4
(C) y = 3x - 4
(D) y = -3x - 4

Answer 1

Letter (D), or y = -3x - 4

Explanation:

A slope of -3 should be self explanatory, and y intercept is determined by the b value in the form y = mx + b. Since b is negative, we are looking for -4. Therefore, your answer is (D).

Hope this helps!
