Question

If P(-9, -4), Q(-7, -1), R(-2, 5), S(-6, -1) are the coordinates of the points, what is the slope of line PQ?

Answer 1

Given :

P(-9, -4), Q(-7, -1), R(-2, 5), S(-6, -1).

To Find :

The slope of line PQ.

Solution :

We know , slope is given by :

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{-9-(-7)}{-4-(-1)}\\\\m=\dfrac{2}{3}$

Therefore, the slope of line PQ is 2/3.

Hence, this is the required solution.
