Summary for 20/8/10's lesson...

Kristin Chai(1)- 20/8/10(Friday)

Linear Graphs
For questions similar to example 07 you must REMEMBER that the final line MUST be a equation nothing else.
Also, y=mx+c. In order to find C we need to know y.Therefore,there will only have 1 unknown.
We can substitute some of the coordinates and we can find out what is C.

Finding the Gradient:
We need to change the equation into y=mx+c.
When the questions say it is parallel that means the gradient is the same.
Also,if the line is horizontal the gradient will be 0.
