Find the equation of the line perpendicular to x-axis and having intercept -2 on x-axis.

Text Solution

Verified by Experts

The equation of the line perpendicular to the x-axis is` x=k`.
It is given that x=k has intercept -2 on the x-axis. This means that the line x=k passes through `(-2,0).`
Therefore`-2=k `
`k=-2`
