# How do you find the slope of x=8?

Jul 15, 2016

The slope of $x = 8$ is undefined

#### Explanation:

slope is defined as $\left(\text{change in "y)/("corresponding change in } x\right)$

...but since $x$ is a constant, the $\text{corresponding change in } x$ will always be zero

...and division by zero is "undefined"
