Question

What is the slope of the line passing through the point (3, −4) and perpendicular to the line y = 3x + 5? Write your answer as a fraction.

Answer 1

I think this problem might have given you some useless info. :)

If you know the slope of one line, it's very easy to find the slope of a line perpendicular to it. (do you know how to do this?)

Answer 2

-1/3

Answer 3

because the slope multiplication is always come -1

Answer 4

Since it's perpendicular, the slope will be -1/3 :)
Negative reciprocal = perpendicular

Answer 5

thank you!! :)
