A qn from June 2007 Qn Coordinate Geometry

Point B is intersection of Line AE & BE
1.find eqn of these 2 lines
2.Solve simultaneously
B= (5,8)


Area of EBC is given
Never use distance to solve this part!

1/2 xBxH = 24
What's the base? What's the height?
Base = EC = (x-3)
Height = Vertical Distance from B to line EC = 4

By simply using the CORRECT base & height strategy allows me more time for the rest of the questions!

C=(15,4)

To find D,
Use Eqn of AD

D=(15,-2)

We have parents
already purchased a copy for their children. Even students buying for themselves
through Bank Transfer.
I was "scolded" by one of the students who bought the
papers "Why didn't you let me know earlier?"
Well, late better than never,
isn't it? ;)

Well, there's only 1 O level and it's really starting. You
decide how you want to spend your time.
