Find the distance of a point $P( x,\ y)$ from the origin.

Given: A point $P( x,\ y)$

To do: To find the distance of point p from the origin.

Ans. we know  if there two points $( x_{1},\ y_{1})$ and $( x_{2},\ y_{2})$,

distance between the two points,$=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

By using the distance formula,

Distance of point $P(x,\ y)$ from the Origin b $=\sqrt{(x-0)^{2}+(y-0)^{2}}$

                                                                         $=\sqrt{(x)^{2}+(y)^{2}}$
