Question

passing through (5,7) and perpendicular to the line containing the points (-2,-1) and (6, -2). write in slope intercept form.

Answer 1

Slope of line passing through (-2,-1) and (6,-2):

m = (-2 + 1)/(6 + 2) = -1/8

Slope of perpendicular line:

m = -1/(-1/8) = 8

y = 8x + b

7 = 8(5) + b

b = -33

y = 8x - 33
