2/5m - 4/5 - 3/5m...combine like terms
-1/5m - 4/5
Well... Basically, you should prove this by SSS property(side-side-side). It's fair to say that the length of a side is equal to itself so The line that cuts through the rectangle is a side for both rectangles. Thus because of the given, all the sides of the triangles are equal to one another. This is a very important trick for geometry(I remember using it a lot).
Hope this helps!
The slope of AB is also -5. This is because parallel lines have equal slopes.
