Answer:
y = x - 16
Step-by-step explanation:
The <em>y-intercept</em> is the value of the function when x = 0.
If f(x) = x - 16, f(0) = 0 - 16 = -16.
A is <em>wrong</em>, because f(0) = -16(0) + 1 = 0 + 1 = 1.
B is <em>wrong</em>, because f(0) = 16(0) + 1 = 0 + 1 = 1.
D is <em>wrong</em>, because f(0) = 0 + 16 = 16.
