Question

9) What is the distance of point A ( -3, 4 ) from the origin ?

A) 7 B) 1 C) 5 D) 4​

Answer 1

Answer:

5

Step-by-step explanation:

√(-3)²+4²

=√9+16

=√25

=5

Answer 2

Answer:

(C) 5

Step-by-step explanation:

We have distance formula to find distance between two points whose coordinates are

(x1,y1)and(x2,y2)

Given by,

Distance between points = √(x1-y1)^2+(x2-y2)^2

Here two given points are O(0,0) and P(- 3, 4).

Applying distance formula we get,

Distance AO is

=√(-3-0)^2+(4-0)^2

=√(-3)^2+4^2

=√9+16

=√25

=5

So,

distance between two given points is 5 units .
