I will give you two int arrays each with a size of 4. These will be the end points of the line.

In what format? 4 numbers can mean anything.

I didn't even pay attention, but your tests aren't enough:

{0,0,100,100}, {0,0,100,150}: both our codes would return true, for this!

and note that once you'll corret that, you'll need to handle floating point errors.

hi,

Sorry, but your kata is way too much of a classic (we already have sevral katas about that kind of stuff). Moreover, it's lacking random tests.
