The distance of a point (2,3) from the x− axis is
Since, we have the distance between two points A(x1,y1) and B(x2,y2) is =√......(i)
Given points A(x1,y1)=(2,3) and the other point lies on x−axis. so the other B(x2,y2)=(2,0) as the the y−ordinate on x− axis is equals to 0 and also this point is closure of A among other points on x−axis.
Substitute the values of given points in equation(i), we get required distance as
Therefore, the distance between two given points is=3 units
Alternatively, the distance of a point from x− axis is the length of its y−coordinate,
In this case, the y-ordinate is 3.
Hence, the required distance is =3units
Therefore, the correct option is A ( 3 units)
