line \(\ldots\ldots\ldots\) and line \(\ldots\ldots\ldots\)
(b) Here is a different grid.
There are four points on this grid that each have
both coordinates that are whole numbers and \(x\)-coordinate \(+\) \(y\)-coordinate \(= 3\)
Plot the four points on the grid. [2 marks]

(0, 3), (1, 2), (2, 1) and (3, 0) plotted with no other points plotted on the grid
B2
B1 at least two of (0, 3), (1, 2), (2, 1) and (3, 0) plotted with up to two other points plotted on the grid or at least four points plotted that would lie on the line \(x + y = 3\) where each \(x\) and \(y\) are not all integers, with no other points plotted on the grid or all four correct coordinates given but not plotted, with no additional coordinates
Additional guidance
Mark intention
Line joining the four correct points with only the four correct points plotted
B2
Line connecting the four correct points but without points plotted
