DID I DO THIS CORRECTLY?

Find the slope-intercept form for the line passing through (-3,3) and perpendicular to the line passing through (-7, 1/2) and (-4, 2/3).

2/3 - 1/2 / -4 - -7 = 1/6 / 3 = 1/18

slope of perpendicular line would be:
18

y-3=18(x--3)

y-3=18(x+3)

y-3=18x+54

The answer that I got: y=18x+57

lalaly · Answer

slope of perpindicular line is -18

dumbcow · Answer

If perpendicular slope is -18, then equation of line is y = -18x -51

y-3 = -18(x+3)
y = -18x -51
