B2 for \(-3x + 11\) or \(y = mx + 11\) (\(m \ne -3\) or 0, \(m\) does not need to be numeric) or \(y = -3x + c\), (\(c\) can be 0, \(c\) does not need to be numeric)
OR
M1 for \(\dfrac{11 - -1}{0 - 4}\) oe
OR
B1 for \(mx + 11\), (where \(m \ne -3\) or 0, \(m\) does not need to be numeric) or \(-3x + c\) (where \(c \ne 11\), \(c\) can be 0, \(c\) does not need to be numeric).
