Distance Formula: Given the two points (x1, y1) and (x2, y2), the distance between these points is given by the formula:
square root of x2-x1 squared +y2-y1 squared
so basically,
1. find the change in x
2. find the change in y
3. square the change in x and the change in y
(x^2) (y^2)
4. add up your change in x^2 +change in y^2
5. fing the square root of ur answer
hope u find it useful
