Question

Distance of point $(-3,4)$ from the origin is .........

• A. $7$
• B. $1$
• C. $5$
• D. $-5$

Answer 1

The correct option is C $5$

Distance of point $(-3,4)$ from the origin

$=$Distance of point $(-3,4)$ from $(0,0)$

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

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

$=\sqrt{9+16}=\sqrt{25}=5$units
