Which statement explains whether y = 4x + 8 is a linear function or a nonlinear function? 1. It is a linear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are on a straight line.

2. It is a nonlinear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are not on a straight line.

3. It is a linear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are on a straight line.

4. It is a nonlinear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are not on a straight line.
