How to find the distance between (3,-2) and (9,2) using pythagorean theorum?

If you imagine the two points on a grid, the difference between their x coordinates is 6 (9-3) and the distance between their y coordinates is 4 (|-2-2|).

In the Pythagorean theorem (a, these would count for the values of a and b, respectively (the legs of the triangle).

So, to find the hypotenuse, which is the distance between the points, square 6 and 4 to get 36 and 16, and find their sum: 52. 52, therefore, is the hypotenuse squared. So, find the square root of 52 to get , or ~7.2111 (exact form: )

From this is derived the distance formula, 

Dbc if u do the math and stuff that what i got let me know if i was wrong
