Answer:
-2
Explanation:
Standard equation of a proportional relationship:
y = kx
We use the given point to find k.
4 = k × (-16)
k = 4/(-16)
k = -1/4
The equation of this proportional relationship is
y = -1/4 x
Now we use x = 8 in the equation just above to find its corresponding y value.
x = 8
y = -1/4 × 8
y = -2
Answer: -2
