Answer:

-7

Step-by-step explanation:

well, y-intercept is value of y when x = 0.

from the problem, we already have the answer, it is -7

but more detailed way is

m = -3

\frac{y - ( - 7)}{x - 0}  =  - 3 \\ y - ( - 7) =  - 3x \\ y =  - 3x - 7 \\

y-intercept is value of y when x = 0

y =  - 3(0) - 7 \\ y =  - 7
