Answer:
y = -x -1
Explanation:
The x- and y-coordinates will be the same for the parallel line, so we only need to find the constant that needs to replace the +8 in the given equation.
y = mx +b
y = -x +b . . . . . with the coefficient of x filled in
-4 = -(3) +b . . . with the given point filled in
b = -1 . . . . .add 3 to both sides
The equation is ...
y = -x -1
