5. Analyzing Lines of Fit
Sign In
Is the rate of change constant for the given (x,y) coordinate pairs?
Linear, see solution.
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.
