OBJECTIVE: To discover the gradient and intercept values of a straight line graph from the linear function.

SUCCESS
CRITERIA: You will be able to rearrange a function into the form y = mx + c and then write down the gradient and intercept of the function.

STARTER: Re arrange the following equations so they all read y = .....

2y = 4x + 18

5y = 10x – 15

4y – 2 = 6x

9y – 18 =27x

4x + 2y = 6

3y – 6x = 15

2y – 3x = 5
