Perpendicular lines have slopes that are negative reciprocals.
so first you must find the slope of the line given
the slope formula is
m=(y₂-y₁)/(x₂-x₁)
now you just plug in the coordinate points that you are given
m=(-2-2)/(0-(-3)
m=-4/3
so the slope of the line given is -4/3, the negative reciprocal of this would be 3/4
The slope of the perpendicular line would be 3/4
