Question

A point is at a distance of 4 units from the x-axis and 2 units from the y-axis. How many values of 'x' exist?
  1. 2


Solution

The correct option is A 2

The perpendicular distance of the point from y-axis is abscissa of the point. Here 2 is the abscissa of the point.

The perpendicular distance of the point from x-axis is ordinate of the point. Here 4 is the ordinate of the point.

On the coordinate plane, points are written in the form of (abscissa, ordinate).

Since the direction is not mentioned,  (2,4),(2,-4) and (-2,-4) are possible.

Therefore, x can have two values 2, -2.
