Given the linear function below

In 2009 the number of vehicle sales in the United States was 10,602 and in 2013 it was 15,884. determine the average rate of change from 2009 to 2013. if x is the number of years since 2009 and f(x) is the number of vehicles sold, find the equation of the line through these two points. assuming f(x) is a linear function, use the equation to predict the number of vehicles sold in 2016.

consider the statement below. Linear functions always have one x-intercept. Give an example if the statement is true or a counterexample if the statement is not true

Let f(x) be the height of a maple tree in inches and x the number of years since 2000. A linear model for the data is f(x) = 9.44x + 84.182. 220 210- 200 190 180 170 160 150 140 130 120 10 100 90 70 60 6. 12 50+ A) To the nearest inch, estimate the height of the maple tree in 2014. inches B) Use the equation to find the year in which the tree will be 249 inches tall.
