Answer:
y=-3x
Step-by-step explanation:
You can plug in the values of x and y to check this:
9=-3(-3) so 9 = 9 which is CORRECT
3=-3(-1) so 3 = 3 which is CORRECT
0=-3(0) so 0 = 0 which is CORRECT
-9 = -3(3) so -9 = -9 which is CORRECT
This shows that the function y=-3x is the correct choice and works for each value in the table.
