Bug: The order of the arguments in the starting function definition is x1, x2, y1, y2, whereas the the order in the test cases is x1, y1, x2, y2.
Technically, this problem is actually requesting the number of unique intersections minus one. For instance in the first case of the test suite, the line crosses the point (5,3) which is shared by four squares, but we count only two, which is the expected behaviour when crossing an edge, but not a vertex: https://imgur.com/a/wCQ6SNG
