Question

Choose the equation of the line passing through the point (4, -2) and perpendicular to y = 1/3x - 7.

y = -3x - 14

y = 3x - 10

y = -3x + 10

y = 3x + 14

Answer 1

y = 3x - 10

Answer 2

?

Answer 3

slope of line perpendicular to your line is -3
since -3 times 1/3 = -1

Answer 4

we have y = -3x + b
plug in (4, -2) to solve for b

Answer 5

@snapbacklive, you have a sign missing in your solution. Remember the slope of the line perpendicular to the first line will be NEGATIVE reciprocal.
