What is the slope of the line that contains the points (2, -6) and (-3, 1)?

Radda [10]

Answer:

The slope is $m=-\frac{7}{5}$

Step-by-step explanation:

The slope of the line passing through $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula;

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

The given line contains;the points (2, -6) and (-3, 1).

$m=\frac{1--6}{-3-2}$

$m=\frac{1+6}{-3-2}$

$m=\frac{7}{-5}$

The slope is $m=-\frac{7}{5}$
