The distance of the point $(9,-12)$ from origin will be ___________.
 

To find the distance between two points , we can use distance formula:

d =  $\sqrt{({\mathrm{x}}_2-{\mathrm{x}}_1{)}^{2 }+{({\mathrm{y}}_2-{\mathrm{y}}_1)}^2 }$

Where $(x_1, y_1) and (x_2,y_2)$coordinates of two points.

Given points are (9, -12 ) and (0, 0), as origins coordinate is (0, 0).

Here, $(x_1, y_1) = (9, -12) and (x_2,y_2) = (0,0)$

 On substitution, we get:
$=\sqrt{{(0-9)}^2+{(0+12)}^2}$
$=\sqrt{{\left(9\right)}^2+{(-12)}^2}$
$=\sqrt{81+144}$
$=\sqrt{225}$
$=15$

The distance of the point $(9,-12)$ from origin will be 15 Units.
