[Calc] Distance Slope and Midpoint finder

[WMD54]

This is a very, very useful program that I wrote and it has saved me a whole lot of time. You enter two coordinate points and it finds the slope of the line that passes in between the two points, the distance between the two points and the midpoint of the line in between the two points. Here's the source and the program is attached on the bottom. DO NOT COPY AND PASTE THE SOURCE INTO A NEW PROGRAM THERE ARE SYMBOLS IN THE PROGRAM THAT ARE NOT SUPPORTED ON A BROWSER SO I HAVE HAD TO CHANGE SOME STUFF. see what you can figure out, and anything you don't get, ask me.

coolio coulda used this in geometry last year

[WMD54]

this stuff just keeps popping up. i'm in pre-cal and i've used it this year so you never know when you'll need it

[xWhite_Shadowx]

u still do a review of it in Alg 2 sonnie
