distance AB
= √ [(x2 - x1)2 + (y2 - y1)2]
= √ [(2.5 - -8.6)2 + (5.5 - -5.4)2]
= √ [11.12 +10.92]
= 15.6

(2.5, -5.4)

(-8.6, 5.5)

(-8.6, -5.4)

y2 - y1
= 5.5 - -5.4
= 10.9

x2 - x1
= 2.5 - -8.6
= 11.1

You can move the graph up-down, left-right if you hold down the "Shift" key and then drag the graph.

Find the distance between the points (3, -4) and (5, 7).

Here, x1 = 3 and y1 = -4; x2 = 5 and y2 = 7

So the distance is given by:

distance AB
= √ [(x2 - x1)2 + (y2 - y1)2]
= √ [(3 - 5)2 + (7 - -4)2]
= √ [22 +112]
= 11.2
