Representations of Relations

Select the rule/equation that best represent the table.

• y = 2x + 1

• y = -2x + 1

• y = x + 7

• y = -3x - 1

Which equation matches the table?

• y = x + 5

• y = 5x

• y = x - 5

• x = y - 5

What rule would explain this input output table?

• The output is 3 times as much as the input.

• The input is 3 times as much as the output.

• The output is 8 times as much as the input.

• The input is 8 times as much as the output.
