Table shows the number of wireless service subscribers in the United States and their average monthly bill in the years from 2000 through 2015
One of the scatter plots suggests a linear model. Use the points at t = 0 and t = 15 to find a model in the form y = mx + b.

The scatter plot for the subscribers suggests a linear model because the points appear to lie on a line.
Since the y-intercept is the y-value, when t=0, we know that b=109.5 from the first point. So, the equation is: y=17.9t+109.5
