(a) On the number line, show the inequality \(\;-2 \leqslant y \lt 1\)(2)
\(n\) is an integer.
(b) Write down all the values of \(n\) that satisfy \(\;-3.4 \lt n \leqslant 2\) (2)
Mark scheme (a)
Scheme
Marks
Correct number line
B2
(2)
Notes
B2: for a fully correct number line e.g. shaded circle at −2, unshaded circle at 1 and a line drawn between them (B1 for a shaded circle at −2 or an unshaded circle at 1 or circles at −2 and 1 with line in between but shading incorrect)
Mark scheme (b)
Scheme
Marks
−3, −2, −1, 0, 1, 2
B2
(2)
(4 marks)
Notes
B2: fully correct values with no extras (B1 for 5 correct values and none incorrect or all 6 correct values with no more than one additional incorrect value)
