Answer:
x = 4
y = -4
Step-by-step explanation:
The zeros of a function are the values of 'x' and 'y' when the other variable is '0'. When x = 0 and y = 0, the value of the other variable is the answer. For the points given (0. -4) and (4, 0) show x = 0 and y = 0.
When x = 0, y = -4, when y = 0, x = 4.
