Which table(s) represent linear functions?

• Table 1, only

• Tables 1 and 2, only

• Tables 1 and 3, only

• Tables 1, 2 and 3.

Which table(s) are nonlinear?

• Table 2, only

• Tables 2 and 3, only

• Tables 1 and 2, only

• Tables 2 and 4, only

Which equations represent linear functions?

• Equations 1 and 2, only

• Equations 1 and 4, only

• Equations 2 and 3, only

• Equations 1, 3, and 4, only

Which answer choice is true?

• The table represents a linear function because there is a pattern for the x-coordinates and y-coordinates.

• The table represents a linear function because the ratio of the change in the y value and the change in the x value is constant.

• The table represents a nonlinear function because the ratio of the change in the y value and the change in the x value is not constant.

• The table does not represent a function because there is more than one output for at least one input.

Which equation(s) represent nonlinear functions?

• Equation 1, only

• Equations 1 and 3, only

• Equations 1, 2, and 3, only

• Equations 1, 2, 3, and 4
