Question

What is the slope of the line through (-7,-2) and (−6,7)?

Answer 1

Answer:

slope = 9  

Step-by-step explanation:

To find the slope of a line that passes through a pair of points, use the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$. Substitute the x and y values of (-7,-2) and (-6,7) into the formula and simplify:

$m = \frac{(7)-(-2)}{(-6)-(-7)} \\m = \frac{7+2}{-6+7} \\m = \frac{9}{1} \\m = 9$

So, the slope is 9.
