Question

TRUE OR FALSE?

If a line has a slope of 5/2, then a perpendicular line would have a slope of -2/5.

Answer 1

yes

Answer 2

Google Crashed.
Here we write it again.
\[\LARGE k\cdot k_1=-1\]
\[\LARGE \frac52 \cdot k_1=-1\]
\[\LARGE k_1=\cfrac{-1}{\cfrac52}\]
\[\LARGE k_1=\cfrac{-2}{5}\]
so it's true ! :)

Answer 3

thank you (:
