23 a. Use the data points (7, 15400) and (13, 22600) to write a linear model of the form: f(t)=mt + b where t is the number of years after 2000 and b is the population in 2000. 15400= m 7+16 7200=6m 22600=m. 13+b m=100 15400 = 1200.7+b f()=1200+ b =15400-8400=7000 b. Use the model from (a) to approximate the population in 2020
