Answer:
y = -5x-21
Step-by-step explanation:
Slope of parallel lines is the same.
To find b:
y = mx + b
Substitute the slope and the point given
-1 = -5(-4) + b
Solve for b
-1 = 20 + b
b = -21
The answer would be -3 because you distribute
The answer is D
To find the constant of proportionality divide y by x.
18/4 = 4.5
