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.
For those who are serious in doing
your best and getting the marks you deserve for your Monday paper, you
should get the step by step solutions today cos price is going up tm(Fri)
