One of the mock papers that DC is attempting had a line from coordinates (0,6) to (6,0). She was asked to choose an equation that represented the line.

I am aware of y = mx + c, where m is the slope and c is the y intercept.

Are they expected to know or is there an easier to way to determine the equation of the line

Try substituting the co-ordinates into the equation.

Are line equations part of KS2 studies ? I thought they were more ks3.

Will CEM have any of these questions ?

I think I read somewhere about co-ordinates being last years Bucks prep papers but like you say I'd be surprised to see this type of question come up in CEM.....then again who knows? :shock:
