Notes
B3: B3 for a correct line between \(x = -2\) and \(x = 3\)
(B2 for a correct straight line segment through at least 3 of (−2, 7) (−1, 4) (0, 1) (1, −2) (2, −5) (3, −8) or for all of (−2, 7) (−1, 4) (0, 1) (1, −2) (2, −5) (3, −8) 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 negative gradient through (0, 1) or for a line with a gradient of −3)
