Find the slope of the line that contains (-2,-2) and (-10,-9)

andrey2020 [161]

Answer:

$\huge \frac{7}{8} \\$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question we have

$m = \frac{ - 9 - - 2}{ - 10 - - 2} = \frac{ - 9 + 2}{ - 10 + 2} = \frac{ - 7}{ - 8} = \frac{7}{8} \\$

We have the final answer as

$\frac{7}{8} \\$

Hope this helps you
