Practice SAC: Linear Modelling (2023)
Student name: …………………………………………………………………(Marks: …………../31)
Q.1 Complete a table of values and plot the graphs of these two linear relations on the same set of
axes.
(i) y = 2 + 5x (1 mark)
x 0 1 2 3 4
Y 2 7 12 17 22
(ii) y = 12 – x (1 mark)
x 0 1 2 3 4
Y 12 11 10 9 8
a. Label both axes and scale them correctly.
b. label the intersection of the two lines on the graph.
c. Label the correct rule on each of these two graphs.
d. Use the CAS now to check your graph. (5 mark)
