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