The first (and most typical) way to find distance of two points is by using the distance formula.

One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
Since they are just next to each other ill take it multiplication and that would be 128 if its not let me know and ill correct it
