Question

When graphed, the x-intercept of a linear function is (-4,0), and the y-intercept is (0,12).

Which of the following equations represents the function?
A. y − 4 = 4(x + 2)
B. y − 6 = 3(x + 2)
C. y + 6 = 2(x + 7)
D. y + 12 = 5(x − 4)

Answer 1

B. y - 6 = 3(x + 2)

Explanation:

Eq. a: y = 4x + 12 (not the answer because if y = 0, x should be -4, but isn't)

b: y = 3x + 12 (correct one because process of elimination)

c: y = 2x + 1 (not the answer because d is not 12, but 1)

d: y = 5x + 8 (not the answer because d is not 12, but 8)
