Just in case you are yet in need of a solution...
Using y = -5x+4, which has a slope of -5
A parallel line would have the same -5 slope.
A perpendicular line would have a 1/5 slope
...
Using the (-10,3) coordinates, solve for the y-intercept
parallel line
3=-5(-10) + b
b = 3 - 50
b = -47
linear equation for the parallel line would be y=-5x-47
..
perpendicular line
3=1/5(-10)+b
b = 3+2
b = 5
linear equation for the parallel line would be y=1/5x+5
...
RED y=-5x+4
GREEN y=-5x-47
BLUE y=1/5x+5
