Question

The distance of the point C(4, −3) from the origin is:​

• A. 3 units
• B. 4 units
• C. 5 units
• D. 7 units

Answer 1

The correct option is C 5 units

Let us consider
points (4, -3) $=(x_1,y_1)$
and (0, 0) $=(x_2,y_2)$.

We know that,distance between any two points is given by:
$d=\sqrt{(x_2-x_1{)}^2+(y_2-y_1{)}^2}$

Now, equating the values
$\Rightarrow d=\sqrt{(0-4{)}^2+(0-(-3){)}^2}\Rightarrow d=\sqrt{16+9}\Rightarrow d=\sqrt{25}\Rightarrow d=5\text{units}$
