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

y2 − y1
= 5.5 − -5.4
= 10.9
x2 − x1
= 2.5 − -8.6
= 11.1

the ∣ AB ∣ =) [(X1, X2) ^ 2 + (Y1, Y2) ^ 2) ^ 2) (1 + k =) (X1, X2) ^ 2,
or < AB =∣X1-X2 < secα=∣Y1-Y2 /sinα,
Where α is the straight line AB inclination Angle and k is the straight line AB slope.
is often used in Function graphics to find distance, and then through distance to find point coordinates word problems.
