a)

If we look at the table closely, we see that we have a constant change of -3. Since every 1 week, 3 pounds are lost, we have a constant change of -3. The data is linear.

b)

The change is NOT constant every week.

First, change is -5

Next, change is -4

Then, change is -3

So, it is non-linear.

c)

The rate for week 1 - week 2 is constant at 168.

If we were to graph, we would have a horizontal line.

So, data is linear.
