Answer:
y = -5x -19
Explanation:
You want the equation of the line parallel to y=-5x+3 through point (-3, -4).
Parallel lines
The equations of parallel lines differ only in their constant. We can find the new constant by using the values at the given point:
y = -5x +b
-4 = -5(-3) +b
b = -4 -15 = -19 . . . . . . subtract 15
The equation is ...
y = -5x -19
