The table shows the relationship between y, the cost to rent a bicycle, and x, the amount of time the bicycle is rented in hours. Part 3: Write a linear equation in slope-intercept form to represent the data shown in this table.

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.
