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

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

anonymous · Answer

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

anonymous · Answer

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

hero · Answer

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