Here the two points given on the graph A and B
To find : The distance in between the two points we know distance in between two point on a graph
=
[tex] \sqrt{ {(x2 - x1)}^{2} } + \sqrt{ {(y2 - y1)}^{2} } [/tex]
The Point A = (0,0)
The point B = (3,6)
so the distance in between points A and B
[tex] \sqrt{ {(0 - 0)}^{2} } + \sqrt{ {(6 - 3)}^{2} } [/tex]
[tex] \sqrt{ {3}^{2} } [/tex]
[tex]3[/tex]
So 3.0 is the distance
Hope it helps
