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=(y_2-y_1)/(x_2-x_1)\\\\m=(-9-(-7))/(-4-(-1))\\\\m=(2)/(3)`

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

Hence, this is the required solution.
