Find the Slope (-8,10) , (-8,-7)

$(- 8, 10)$ , $(- 8, - 7)$

Step 1

Slope is equal to the change in $y$ over the change in $x$ , or rise over run.

$m = \frac{change in y}{change in x}$

Step 2

The change in $x$ is equal to the difference in x-coordinates (also called run), and the change in $y$ is equal to the difference in y-coordinates (also called rise).

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Step 3

Substitute in the values of $x$ and $y$ into the equation to find the slope.

$m = \frac{- 7 - (10)}{- 8 - (- 8)}$

Step 4

Simplify.

Multiply $- 1$ by $- 8$ .

$\frac{- 7 - (10)}{- 8 + 8}$

Add $- 8$ and $8$ .

$\frac{- 7 - (10)}{0}$

The expression contains a division by $0$ . The expression is undefined.
