Foundation June 2022 Paper 2 Q17
17 On the grid below, draw the graph of \(y = 4 - x\) for values of \(x\) from \(-2\) to 4 (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| Line Drawn | B3 | for a correct line between \(x = -2\) and \(x = 4\) |
| (B2 | for a correct straight-line segment through at least 3 of \((-2, 6), (-1, 5), (0, 4), (1, 3), (2, 2), (3, 1), (4, 0)\) or for all of these points plotted but not joined or for a line drawn with a negative gradient through \((0, 4)\) and clear intention to use a gradient of \(-1\), eg a line through \((0, 4)\) going across 1 square and down 1 square) | |
| (B1 | for at least 2 correct points stated or plotted or a line drawn with negative gradient through \((0, 4)\) or a line with gradient \(-1\)) |
Additional guidance
Accept freehand line drawn
Ignore any incorrect points
Table of values
| \(x\) | \(-2\) | \(-1\) | 0 | 1 | 2 | 3 | 4 |
|---|---|---|---|---|---|---|---|
| \(y\) | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
Ignore any incorrect points
Coordinates may be in a table or working
Do not accept \(y = 4\) drawn
