A table of values is usually used to show a relationship between two variables.
If one amount is always twice another amount, the relationship could be expressed as follows:
y: One amount
x: Another amount
y = 2x
A table of values can be made by substituting values for either x or y.
A table of values using the numbers above is shown below.
A table showing the relationship between distances measured in both centimetres and metres is shown below.
Based on the table of values above, the relationship between "distance in metres" and "distance in centimetres" could be expressed as follows:
Let y represent "distance in metres", and let x represent "distance in centimetres".
Based on the table of values, it is reasonable in this case to conclude that y = 100x.
