2.Complete the table of values for f: y = 3x − 1.

4 P4/4

x−1012

y-4-125All values right

3.Do P(4, 5) and Q(−2, −3) lie on g: y = 1.5x − 1?

4 P3/4

P: 1.5 · 4 - 1 = 5 → P is on gChecked correctly

Q: 1.5 · (-2) - 1 = -2 → not on g1.5 · (–2) – 1 = –4

4.Plan: €8 base fee, €2 per GB. Equation and cost for 5 GB?

4 P4/4

y = 2x + 8Equation fits

y = 2 · 5 + 8 = 18 → €18Cost is right

5.Find the zero of h: y = −2x + 6.

3 P3/3

0 = -2x + 6 | - 6Well rearranged

-6 = -2x | : (-2)Divided correctly

x = 3Zero at x = 3

6.Are g: y = 2x + 1 and h: y = 2x − 4 parallel? Explain.

3 P2/3

Yes, they look equally steep.Explain with m:
both have m = 2

Show all your working. Each part can be solved on its own.

1.Recognising and drawing linear functions

7 P

a)Find the equation of the line through A(−1, 1) and B(2, 7).

m = (7 - 1) : (2 + 1) = 6 : 3 = 2Slope is right

y = 2x + tGood set-up

1 = 2 · (-1) + tA put in correctly

1 = -2 + t → t = -1Check the sign!
t = 1 + 2 = 3

y = 2x - 1FTFollow-on error:
y = 2x + 3

42/4

b)Draw the graph of g: y = −¾x + 2. Axes from −5 to 5.

Axes scaled correctly
t = 2 plotted correctly
Slope triangle: 4 right, 3 down
Neatly drawn!
