Question

What is the slope of any line perpendicular to the line passing through `(3,8)` and `(-2,-15)`?

Answer 1

`-5/23`

Explanation:

The slope of the line joining `(x_1, y_1) and (x_2, y_2) = (y_2-y_1)/(x_2-x_1)`.

The slope of the perpengicular line is the negarive reciprocal.

The slope of the given line is `23/5`and irs negative reciprocal is `-5/23`.
