The slope of a line which passes through (-3, 4) & (5, -8) :
m = -8-4 / 5+3 = -12/8 = -3/2
The slope of perpendicular line = -1/m = 3/2
y - 4 = (3/2)(x + 3)
y = (3/2)x + 17/2
m = -8-4 / 5+3 = -12/8 = -3/2
The slope of perpendicular line = -1/m = 3/2
y - 4 = (3/2)(x + 3)
y = (3/2)x + 17/2
-
(4 - (-8))/(-3 - 5)
-12/8
y+8= (-12/8)(x-5)
-12/8
y+8= (-12/8)(x-5)
