(From their table of values) M1 ft for plotting at least 2 of their points (any points from their table must be correctly plotted) A1 for correct line from \(x = -2\) to \(x = +2\)
(Use of \(y = mx + c\)) M1 for line drawn with gradient of 2 or line drawn with a \(y\) intercept of 5 and a positive gradient) A1 for correct line from \(x = -2\) to \(x = +2\)
