Q1. A table of values for a linear function is given. Fill in the missing value.

x	-1	0	1
y	2	7

Calculate m.

m =

Q2. Find the equation of the given linear function.

x	-4	0	4	20
f(x)	-3	-4	-5	-9

F(x)

Q3. Decide which of the two given functions is linear and find its equation.

x	0	1	2	3	4
f(x)	8	11	14	17	20
g(x)	10	11	16	15	20

(so basically f(x) or g(x) and input the results for the one that is linear)
