Checkpoint 2

I found some of these functions in checkpoint 2 to be a little bit
trickier to write. I wasn’t always sure what was going on with each
function and often had to look back and really think about what each
function was doing. Particularly with the clamp and ratio functions I
had a more difficult time understanding what the purpose of the function
was in the grand picture of making the scatter plot, but the more I
played around with the functions the more sense it made. I did get stuck
once with the lists for the get_x and get_y values and while I thought I
needed to create a list, I was missing the piece about how to add to
the list. Checking in with classmates on Discord helped me to move
past that roadblock.
