A line and three points are shown on the grid. The line on the grid contains the points (–1, 2) and (5, –2). The point is located at (–4, –4) on the grid. Find the coordinates of points three points that lay on a line, which passes through point P and is perpendicular to line c.

try using desmos. Its an online graphing calculator that works wonders
slope of line c = (-2-2)/(5+1) = -4/8 = -2/3
slope of perpendicular is then 3/2
so
y = 3/2 x + b
point (-4, -4)
-4= (3/2)(-4) + b
-4 = -6 + b
b = 2
so y = (3/2) x + 2
go ahead, find 3 points
