Find the Slope (2,-2) , (9,3)

$(2, - 2)$ , $(9, 3)$

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.

$m = \frac{3 - (- 2)}{9 - (2)}$

Step 4

Simplify.

Simplify the numerator.

Multiply $- 1$ by $- 2$ .

$m = \frac{3 + 2}{9 - (2)}$

Add $3$ and $2$ .

$m = \frac{5}{9 - (2)}$

Simplify the denominator.

Multiply $- 1$ by $2$ .

$m = \frac{5}{9 - 2}$

Subtract $2$ from $9$ .

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

Step 5

Find the Slope (2,-2) , (9,3)
