Question

Any two points P(-3, 0)and Q(5, 0) are on XY plane, then write the distance  between these points​

Answer 1

Step-by-step explanation:

Distance between a point from the origin

Suppose a point P(x, y) in the xy –

Distance Formula

Let us calculate the distance between point P and the origin. P is x units away from y-axis and y units away from the x-axis.

By Pythagoras theorem,

OP2 = x2 + y2

OP = x2 + y2

Therefore distance between any point (x, y) in xy-plane and the origin (0, 0) is x2 + y2−−−−−−−√.
