Equation for a line

Post by gulat »

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 ?
