Problem
Numeric Response Use the following information to answer the next two questions In the function below it is possible to determine $x$ and $y$ intercepts: \[ y=-4 x-16 \] Numeric Response 4. What is the $y$-intercept of this function? Express your answer as a whole number. (Record your answer in the numerical-response section below.) Your answer:
Solution
Step 1 ：The y-intercept of a function is the point where the line crosses the y-axis. This occurs when x = 0.
Step 2 ：So, to find the y-intercept, we can substitute x = 0 into the equation and solve for y.
Step 3 ：Substituting x = 0 into the equation gives y = -4*0 - 16 = -16.
Step 4 ：Final Answer: The y-intercept of the function is \(\boxed{-16}\).
