The perpendicular distance of the point P (3, 4) from the y-axis is
a. 3
b. 4
c. 5
d. 7

Solution:

In the Cartesian plane, the horizontal line is called the x-axis and the vertical line is called the y-axis.

Abscissa or the x-coordinate of a point is its distance from the y-axis and the ordinate or the y-coordinate is its distance from the x-axis.

In the coordinates (x, y), x is the abscissa and y is the ordinate.

The point given is P (3, 4)

The perpendicular distance of the point P from the y-axis is 3.

Therefore, the perpendicular distance from the y-axis is 3.

✦ Try This: The perpendicular distance of the point P (2, 3) from the y-axis is a. 3, b. 2, c. 2, d. 8

In the Cartesian plane, the horizontal line is called the x-axis and the vertical line is called the y-axis.

Abscissa or the x-coordinate of a point is its distance from the y-axis and the ordinate or the y-coordinate is its distance from the x-axis.

In the coordinates (x, y), x is the abscissa and y is the ordinate.

The point given is P (2, 3)

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

Therefore, the perpendicular distance from the y-axis is 2.
