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

Thank you soooooooo much, I will for sure watch them. <3
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 x1 minus x2 all to 2nd power plus y1 minus y2 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.
