This model is of the form f(x) = mx + b. Determine what m and b signify. 3) The population, in millions, of a city t years after 1990 is given by P(t) =2.8+ 0.11t.
It means that the population started at 2.8 million, and that it increased by 0.11 million each year. M stands for slope, b stands for the y intercept.
