Question

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

• A. $7$ units
• B. $1$ unit
• C. $5$ units
• D. $-5$ units

Answer 1

Answer: (C)

$5$ units

The distance between two points $=d=\sqrt{(x_1-x_2{)}^2+(y_1-y_2{)}^2}$

The distance between the points $(0,0)$ and $(-3,4)$ be $D$

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

$D=\sqrt{9+16}$

$D=\sqrt{25}$

$D=5$
