# Question #046e2

$x = - 5$ is parallel to y-axis. So, there is no meeting with y-axis to make an intercept. Being perpendicular to x-axis, its slope is tan ${90}^{o} = \infty$.
Compare the equation $x = - 5$ with the form $x = \frac{y}{m} + a$.
$\frac{1}{m} = 0 \left(m = \infty\right)$ and the x-intercept a =$- 5$..
