and

solution

Look at the values of the input,

and the output,

Input (y)	1	2	3	4
Output (c)	4	8	12	16

Find how the inputs and outputs are related.

Input (y)	1	2	3	4
Output (c)	1 × 4 = 4	2 × 4 = 8	3 × 4 = 12	4 × 4 = 16

Each output is 4 times the input. You can write this rule as an equation in more than one way. Here are two ways to write the equation:
