4MA0 Higher January 2016 Paper 4 Q12
12 Find an equation of the line that is parallel to the line \(y = 4 - 2x\) and passes through the point (3, 7)
(3)
| Scheme | Marks |
|---|---|
| \(m = -2\) | M1 |
| \(c = 13\) | M1indep |
| \(y = -2x + 13\) | A1 |
| (3) |
Notes
M1: For recognising gradient = −2, eg \(y = -2x + c\) where \(c \neq 4\)
M1indep: \(c = 13\)
A1: oe e.g. \(y - 7 = -2(x - 3)\)
SCB2 for \(-2x + 13\)
M2 for \(7 = -2 \times 3 + c\)
