Given two vectors p1 and p2, return the slope of a line that passes through p1 and p2.
Examples:
Input [p1,p2] = deal([0,1],[1,3])
Output m = 2
Input [p1,p2] = deal([-2,0],[0,1])
Output m = 0.5

P.S. This is supposed to be a beginner problem; there is no actual difficulty or challenge ?
Thanks for contributing a problem, Ashley. I think it's good to have problems that cover a range of difficulty so that players of all levels can engage with Cody. Your problem's description is clear and concise, and it has a decent number of tests: others recommend at least four tests to discourage lookup solutions.
One suggestion is to use the search tool to check whether others have written similar problems. In this case Cody Problem 43546 is similar. I wrote two problems that I later learned repeat existing problems. Now I check and change the idea if I find a similar existing problem.
