Graph

Axes are drawn in the correct direction, uniform scale for – 3 x 4 and 3 y – 33

9 points and 2 points* plotted accurately

Smooth and continuous curve without straight line(s) and passes through all the 9 correct points for – 3 x 4

Notes : (1) 7 or 8 points plotted correctly, award K1

(2) Other scale being used, subtract 1 mark from the KN marks obtained.

c ) (i) x = 1.7, -3 < y < -5

(ii) y = -26, 3.5 < x < 3.7

Note : Do not accept the values of x and y obtained by calculation

Identify the equation or equivalent

The straight line drawn correctly

The values of x : -2.7 < x < -3

3.0 < x < 3.3

Notes : (1) Award N mark(s) if the value(s) of x shown on the graph

(2) Do not accept the value(s) of x obtained by calculation
