Question #046e2

Answer 1

`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 = oo`.

Explanation:

Compare the equation `x = -5` with the form `x = y/m + a`.
`1/m = 0 ( m=oo )` and the x-intercept a =`-5`..
