-2/7
-7/2
7/2

Answer 1

To find a perpendicular line, find the negative reciprocal of the given line.

Answer 2

is that -7/2?

Answer 3

That's the reciprocal. We need to find the negative reciprocal, which is 7/2 (notice that two negatives cancel each other out)

Answer 4

It's the Negative reciprocal of the slope of your original line

Answer 5

Right, so am all I doing basically is flipping it around and making them both positive??
