Notes
B3: for a correct line between \(x = -1\) and \(x = 4\)
B2 for a correct straight line segment through at least 3 of (−1, −3) (0, −1) (1, 1) (2, 3) (3, 5) (4, 7) or for all of (−1, −3) (0, −1) (1, 1) (2, 3) (3, 5) (4, 7) plotted but not joined
B1 for at least 2 correct points stated (may be in a table) or plotted or for a line drawn with a positive gradient through (0, −1) or for a line with a gradient of 2
