Question

The equation to the side of a triangle are x – 3y = 0, 4x + 3= 5 and 3x + y = 0. The line 3x – 4y = 0 passes through 

Solution

Correct option is

The orthocenter of the triangle.

The three equations of straight lines from a right-angled triangle whose orthocenter is at (0, 0) where right angle is formed. The line 3x – 4y = 0 passes through origin i.e. orthocenter.
