I gave you the formula for this before when you asked..

anonymous · Answer

Distance formula is: $$
d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
$$

Okay how do you tell the difference between x^2, x^1.. Y2, y1 ??

anonymous · Answer

Call (1,2) point 1, and (4,6) point 2. So, $x_1=1, x_2=4, y_1=2, y_2=6$

anonymous · Answer

You can pick either point as point 1, distance between two points is the same regardless of which direction you go.

anonymous · Answer

Wait isnt 6 x2, 2 x1... 4 y2 & 1 y1??

anonymous · Answer

Points are (x,y), not (y,x)

anonymous · Answer

I'm so confused....

anonymous · Answer

x coordinate -------------> (x, y) <-------------------- y coordinate
                      (x1)                  (1, 2)            (y1)
                      (x2)                  (4, 6)            (y2)
