(b) 
Step-by-step explanation:
Given
The attached table
Solving (a): The rule of the table in words
First, we calculate the slope (m)

Using:


So, we have:



The equation is calculated using:

Using:

We have:


Make y the subject


Hence, the rule is:
Multiply the input (x) by 2 and add 5 to the result of the product
(b): The rule, in algebra
As solved in (a), the rule is:

Step-by-step explanation:
= (15 − 3) ÷ (2 + 1) × (8 − 6)
BODMAS rule
= (12) ÷ (3) × (2)
= (12/3) × (2)
= 4 × 2
= 8
