Question

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

Answer 1

Distance of any point from the origin according to the distance formula is,

Distance = √(y-0)^2+(x-0)^2 = √x^2+y^2

So, here,
Distance = √ (3)^2+(-4)^2 = √ 9+16 = √25 = 5 units

Answer 2

To find OA.
By Pythagoras theorem,
$\: \: \: \: \: \: \: OA = \sqrt{ {4}^{2} + {3}^{2} } \\ = > OA = \sqrt{25} = 5units.$
