The table below shows the depth of a hole as it is dug over time.
time depth
(minutes) (inches) |
4.5
6 | 9.0
9
12.5 |
15 20.0
36.0
was the hole dug at a constant rate? if so, what is the constant of proportionality?
if not, how do you know the rate of digging was not constant? (asap)

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.
