Question

Find the slope of the line through P(−5, 1) and Q(9, −5)?

Answer 1

`-3/7`

Explanation:

The slope `m` of the line passing through the points `(x_1, y_1)\equiv(-5, 1)` & `(x_2, y_2)\equiv(9, -5)` is given by following formula

`m=\frac{y_2-y_1}{x_2-x_1}`

`=\frac{-5-1}{9-(-5)}`

`=-6/14`

`=-3/7`
