Distance between two points AB
= √ [(x2 − x1)2 + (y2 − y1)2]
= √ [(2.5 − -8.6)2 + (5.5 − -5.4)2]
= √ [11.12 +10.92]
= 15.6

Let A(X1,Y1) and B(X2,Y2),
Then |AB|=√[(X1-X2)^2+(Y1-Y2)^2]=√(1+k^2) (X1-X2)^2,
Or |AB|=|X1-X2|secα=|Y1-Y2|/sinα,
Where α is the inclination angle of line AB, and k is the slope of line AB.
It is often used in application problems to find the distance in a function graph and then find the coordinates of a point through the distance.
