Question

Find the distance between the point A (9,-7) and the origin.

Answer 1

$\sqrt{ {(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2} } \\ \\ = > \sqrt{ {9}^{2} + { - 7}^{2} } \\ \\ = > \sqrt{130}$

Answer 2

Answer:-

Formula for distance of a point from origin is √x²+y²

Distance=√(9)²+(-7)²

=√81+49

=√130
