A conjecture and the two-column proof used to prove the conjecture are shown. A right angled triangle P Q R. A ray extends horizontally left to QR. A ray extends down to the right of QR. The interior angle is labeled as 1 and 2.

Drag an expression or phrase to each box to complete the proof.

Which statement best explains whether the table represents a linear or nonlinear function? input (x) output (y) 2 5 4 10 6 15 8 20 it is a linear function because the input values are increasing. it is a nonlinear function because the output values are increasing. it is a linear function because there is a constant rate of change in both the input and output. it is a nonlinear function because there is a constant rate of change in both the input and output.
