One of the scatter plots clearly suggests a linear model. Use the points at t = 10 and t = 20 to find a model in the form y=mx+b.y=mx+b.

(10, 109.5)(20,300.5)
Slope=191/10 19.1
y-109.5=19.1(x-10)
y-109.5=19.1x-19.1
y=19.1x-81.5

In 1995 There were 33.8 million subscribers with an average local monthly bill of $51.00. Add these points to the scatter plots. Do the 1995 points match well with the trends in the rest of the data?
