$(0, 1)$ ,

$(1, 0)$

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.

$m = \frac{0 - (1)}{1 - (0)}$

Step 4.1.1

Multiply

$- 1$ by

$1$ .

$m = \frac{0 - 1}{1 - (0)}$

Step 4.1.2

Subtract

$1$ from

$0$ .

$m = \frac{- 1}{1 - (0)}$

Step 4.2.1

Multiply

$- 1$ by

$0$ .

$m = \frac{- 1}{1 + 0}$

Step 4.2.2

Add

$1$ and

$0$ .

$m = \frac{- 1}{1}$

Step 4.3

Divide

$- 1$ by

$1$ .

$m = - 1$
