Exercise 33 Page 198

Is the rate of change constant for the given (x,y) coordinate pairs?

Linear, see solution.

Practice makes perfect

We are given a table of (x,y) coordinate pairs and want to know if the relation between them is a linear function. Let's pay close attention to the given table.

We can see that as x coordinates increase by 2, the y coordinates decrease by - 5. The rate of change is constant and so the function is linear.
