Question
The distance of P (3, 5) from x-axis is
- 3
- 5
- -3
- 2
Hint:
We are given a point. We are asked it’s distance from axis.
The correct answer is: 5
The given point is P(3,5)
We have to tell it’s distance from x-axis.
The x coordinate of a point gives its distance from x-axis. So, the distance of any point from x-axis is the x coordinate of the point.
Here the x coordinate is 3.
So, the distance of the point P from x-axis is 3.
The distance of a point from any axis is given by the respective coordinate of the point.
