Find the slope of the line passing through the points , (-9, -3) and (7, -7).

Solution:

The slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate of that line.

Given, the points (-9, -3) and (7, -7).

We have to find the slope of the line passing through the given points.

The slope of the line passing through the two points is given by

\(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=m\)

\(\\m=\frac{-7-(-3)}{7-(-9)}\\m=\frac{-7+3}{7+9}\)

m = -4/16

m = -1/4

Therefore, the slope of the line is -1/4.

Find the slope of the line passing through the points , (-9, -3) and (7, -7).

Summary:

The slope of the line passing through the points (-9, -3) and (7, -7) is m = -1/4.
