The midpoint of a line A(ax,ay) and B (bx, by)

=

((ax+bx)/2, (ay+by)/2)

So in the given example the midpoint appears to be (1/2, 1/2) when u use both eq 1 and eq 2.


Hence, Ans - C

That's actually a great idea! :-D I wish that suggestion would have came up a few weeks ago though, because I am taking my test tomorrow! :? hehe... *feeling nervous*... so if I fail, I'll definitely be back to take up on your advice
