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
