Question

Distance of point A ( - 3, 4) from the origin is ​

Answer 1

Answer:

5 units

Step-by-step explanation:

√(-3)^2+(4)^2

√9+16

√25

5

Answer 2

Answer:

​

5

Step-by-step explanation:

A =( - 3, 4) and B= (0,0)

Formula for distance between two points (x1,y1) and (x2,y2)

$\sqrt{(x2-x1)^2+(y2-y1)^2}$

x1=-3 , x2=0 , y1=4 , y2=0

$\sqrt{(0+3)^2+(0-4)^2}$ = $\sqrt{3*3+4*4}$

                                = $\sqrt{25}$

                                = $\sqrt{5*5}$

                                = 5

Therefore, the distance of point A ( - 3, 4) from the origin is ​

5.
