| (3) | |
| (3 marks) |
Notes
B3: for \(y = -\dfrac{1}{2}x + 1\) oe but must be in form \(y = mx + c\)
eg \(y = -0.5x + 1\)
(B2 for \((L =)\, -\dfrac{1}{2}x + 1\)
or for \(y = -\dfrac{1}{2}x + c\)
or for \(y = mx + 1\) where \(m \neq 0\)
or for a correct equation in the incorrect form eg \(2y + x = 2\))
(B1 for \((L =)\, -\dfrac{1}{2}x + c\)
or \((L =)\; mx + 1\) where \(m \neq 0\)
or \(m = -\dfrac{1}{2}\) or gradient = \(-\dfrac{1}{2}\) oe eg \(\dfrac{3 - (-1)}{-4 - 4}\))
