Find the Slope (3,5) , (8,15)

$(3, 5)$ , $(8, 15)$

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.

$m = \frac{15 - (5)}{8 - (3)}$

Step 4

Simplify.

Simplify the numerator.

Multiply $- 1$ by $5$ .

$m = \frac{15 - 5}{8 - (3)}$

Subtract $5$ from $15$ .

$m = \frac{10}{8 - (3)}$

Simplify the denominator.

Multiply $- 1$ by $3$ .

$m = \frac{10}{8 - 3}$

Subtract $3$ from $8$ .

$m = \frac{10}{5}$

Divide $10$ by $5$ .

$m = 2$

Step 5

Find the Slope (3,5) , (8,15)
