Question

What is the equation of a line perpendicular to the x axis that goes
through (5,5)?*

Answer 1

To understand the equation of a line which is perpendicular to x axis, let us consider the figure given below. In the figure above, clearly the line L is perpendicular to x-axis and passing through the value "c" on x- axis. Hence, the equation of a line perpendicular to x axis is x = c.
