11
(a) Write down the equation of a straight line parallel to \(\quad y - 2x = 9\) [1 mark]
(b) A straight line
- has gradient 5
- passes through the point (3, 7)
Circle the equation of the line. [1 mark]
- \(y = 3x - 2\)
- \(y = 3x + 7\)
- \(y = 5x\)
- \(y = 5x - 8\)
| Answer | Mark | Comments |
|---|---|---|
| \(y = 2x + c\) or \(y - 2x = c\) | B1 | oe \(c \ne 9\) |
Additional guidance
| Answer \(y = 2x + c\) or \(y - 2x = c\) (any letter for \(c\)) | B0 |
| \(y - 2x + 1 = 9\) | B1 |
| \(y - 2x + 1 = 10\) | B0 |
