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
