I never could remember the distance formula either.....until I finally understood where it came from!

Here's a video that explains it: https://www.youtube.com/watch?v=nyZuite17Pc

Also, I remember this answer from a while back: https://web2.0calc.com/questions/i-needs-help_1

If you dont want to look at those answers (you really should!!!!) ...the short answer is.........

d = \(\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)

I always remember this formula as the square root of the sum of the difference of the x-coordinates squared and the difference of the y-coordinates squared.

For me, knowing how to say the formula in words is better than knowing that the distance formula is "the square root of x_{1 }minus x_{2 }all to 2nd power plus y_{1} minus y_{2} to the 2nd power.

The same applies for the midpoint formula.

I remember it as the ordered pair of the average of the x-coordinates and y-coordinates.
