Higher November 2020 Paper 2R Q12
12 Find the gradient of the straight line with equation \(\;5x + 2y = 7\)
(2)
| Scheme | Marks |
|---|---|
\(y = \dfrac{7 - 5x}{2}\) or \(y = \dfrac{7}{2} - \dfrac{5}{2}x\) or \(y = 3.5 - 2.5x\) or \(2y = 7 - 5x\) oe | M1 |
| −2.5 | A1 |
| (2) | |
| (2 marks) |
Notes
M1: for making \(y\) or \(2y\) the subject
Allow \(y = -\dfrac{5}{2}x + c\) oe
A1: for \(-\dfrac{5}{2}\) or −2.5
(corrected from the printed mark scheme: it prints “Total 3 marks”; the question is worth 2 marks)
