Question

The distance of a point P $(-3,-4)$ from the origin is __ units.

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is D 5

The distance of a point $(x,y)$ from the origin $(0,0)$ is $\sqrt{(x-0{)}^2+(y-0{)}^2}=\sqrt{x^2+y^2}$

So, the distance of a point P $(-3,-4)$ from the origin $(0,0)$ is $\sqrt{(-3-0{)}^2+(-4-0{)}^2}=\sqrt{3^2+4^2}=5$ units
