Notes
B3: for a correct line between \(x = -2\) and \(x = 3\)
(B2 for a correct straight line segment through at least 3 of (−2, −2) (−1, −1.5) (0, −1) (1, −0.5) (2, 0) (3, 0.5)
or
for all of (−2, −2) (−1, −1.5) (0, −1) (1, −0.5) (2, 0) (3, 0.5) 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 0.5)
