Find the Slope and y-intercept (2,1) , (2,6)

$(2, 1)$ , $(2, 6)$

Step 1

Find the value of the slope.

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

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

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).

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

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

$m = \frac{6 - (1)}{2 - (2)}$

Simplify.

Multiply $- 1$ by $2$ .

$\frac{6 - (1)}{2 - 2}$

Subtract $2$ from $2$ .

$\frac{6 - (1)}{0}$

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

Undefined

Step 2

Since the slope is undefined, this is a vertical line. Vertical lines have no y-intercept.

No y-intercept

Step 3

The slope is undefined and there is no y-intercept.

Slope: Undefined

No y-intercept
