Find the Slope (-4,-4) , (2,5)

$(- 4, - 4)$ , $(2, 5)$

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.

$m = \frac{5 - (- 4)}{2 - (- 4)}$

Step 4

Simplify.

Simplify the numerator.

Multiply $- 1$ by $- 4$ .

$m = \frac{5 + 4}{2 - (- 4)}$

Add $5$ and $4$ .

$m = \frac{9}{2 - (- 4)}$

Simplify the denominator.

Multiply $- 1$ by $- 4$ .

$m = \frac{9}{2 + 4}$

Add $2$ and $4$ .

$m = \frac{9}{6}$

Cancel the common factor of $9$ and $6$ .

Factor $3$ out of $9$ .

$m = \frac{3 (3)}{6}$

Cancel the common factors.

Factor $3$ out of $6$ .

$m = \frac{3 \cdot 3}{3 \cdot 2}$

Cancel the common factor.

$m = \frac{3 \cdot 3}{3 \cdot 2}$

Rewrite the expression.

$m = \frac{3}{2}$

Step 5

Find the Slope (-4,-4) , (2,5)
