Question

Which ordered pair represents the y-intercept of the graph of the equation y = –4x – 7?

A. (–7, 0)
B. (–4, 0)
C. (0, –4)
D. (0, –7)

Answer 1

D. (0,-7)

Explanation:

Answer 2

If y = –4x – 7, the x-intercept is found by setting y=0 and solving for x:

0 = –4x – 7 => 4x = -7, or x = -7/4 The x-intercept is (-7/4, 0).

The y-intercept is found by setting x = 0 and reading off the value of y:

y = –4x – 7 => y = 0 - 7, or y = -7. The y-intercept is (0, -7).
