Question

Which linear function is represented by a graph with a y-intercept of −16 ? y=−16x+1 y=16x−1 y=x−16 y=x+16

Answer 1

y = x - 16

Explanation:

The y-intercept is the value of the function when x = 0.

If f(x) = x - 16, f(0) = 0 - 16 = -16.

A is wrong, because f(0) = -16(0) + 1 = 0 + 1 = 1.

B is wrong, because f(0) = 16(0) + 1 = 0 + 1 = 1.

D is wrong, because f(0) = 0 + 16 = 16.
