Question

What is the distance of the point $(-3,4)$ from the origin?

Answer 1

Consider the given points.

$A(-3,4),B(0,0)$

We know that the distance between two points

$d=\sqrt{{(x_2-x_1)}^2+{(y_2-y_1)}^2}$

$d=\sqrt{{(0-(-3))}^2+{(0-\left(4\right))}^2}$

$d=\sqrt{{\left(3\right)}^2+{\left(4\right)}^2}$

$d=\sqrt{9+16}$

$d=\sqrt{25}$

$d=5units$
