Question

The table shows how the length of a fish

changes over time.

Find the relationship between x, the time in

years, and y, the length in centimeters

Answer 1

`y=4.5* x`

Explanation:

Solving;

`y=4.5* x`

when x=3,

`y=4.5*3=13.5` centimeters

when x=4

`y=4.5*4=18` centimeters

when x=7

`y=4.5*7=31.5` centimeters

when x=10

`y=4.5*10=45` centimeters
