1.

Distance of point (-3,4) from the origin is ...... .Fill in the blank using correct alternatives.(A) 7 (B) 1 (C) 5 (D) -5

Answer» USE DISTANCE formula,
We know, if TWO POINTS (x₁, y₁) and (x₂,y₂) are given,
then distance between them = \bf{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}

Now, we have to find distance between (-3,4) and ORIGIN e.g., (0,0)
so, distance between them = \bf{\sqrt{(0+3)^2+(0-4)^2}}
= \bf{\sqrt{9+16}=5}
hence, option (c) is correct
