slope is undefined
Work Step by Step
Solve for $x$ to obtain: $x-2=0 \\x-2+2=0+2 \\x=2$ This means the given equation is equivalent to $x=2$. RECALL: (1) The graph of the equation $x=h$ is a vertical line. (2) A vertical line has an undefined slope. Thus, $x=2$ is a vertical line whose slope is undefined.
