Question

Answer the following question:

Obtain the equation of the line containing the point (2, 4) and perpendicular to the Y−axis

Answer 1

Equation of a line perpendicular to Y-axis i.e., parallel to X-axis, is of the form y = k.

Since the line passes through (2, 4),

k = 4

∴ The equation of the required line is y = 4.
