Answer:

y = 4

Step-by-step explanation:

This looks like a direct variation or constant of proportionality question.

If so, then use the following explanations:

y = kx

-8 = 2k

k = -8 ÷ 2

k = -4

y = -4x

when x = -1

y = -4(-1)

y = 4

If this is the correct answer, then please make this the brainliest answer.
