The slope of $x-5=0$ is "undefined".

$x-5 =0$
or equivalently $x = 5$
is a vertical line.

Slope for any two points $(x_1,y_1) and (x_2,y_2)$ is defined as
$(y_2-y_1)/(x_2-x_1)$

$x_2 and x_1$ must both be $=5$ based on the equation
so any attempt to evaluate the slope results in an attempt to divide by zero.

$x-5=0$ is a vertical line
