An input-output table is a two-column table in which the same rule is
applied to each input value resulting in the corresponding output values.
Find a rule that relates the numbers in the first column to the numbers in the second column.
x | rule |
y |
2 | × 20 | 40 |
5 | × 20 | 100 |
8 | × 20 | 160 |
11 | × 20 | 220 |
The y-values are 20 times the corresponding x-values.
Find a rule that relates the numbers in the first column to the numbers in the second column.
