The distance of a point P(x, y) from the origin O(0, 0) is given by OP=__

Naily [24]

Answer:-

$\boxed{\sf \sqrt{x^2+y^2}}$

Explanation:-

P(x,y)
O(0,0)

We know distance formula

$\boxed{\sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

$\\ \sf\longmapsto OP=\sqrt{(0-x)^2+(0-y)^2}$

$\\ \sf\longmapsto OP=\sqrt{(-x)^2+(-y)^2}$

$\\ \sf\longmapsto OP=\sqrt{x^2+y^2}$
