In 1990, people in the United States spent about $285.7 billion on recreation. In 1995, they spent $402.5 billion. Write a linear equation in slope-intercept form to model the amount (in billions of dollars) spent on recreation since 1990. *please look at it* (:

Question

In 1990, people in the United States spent about $285.7 billion on recreation.  In 1995, they spent $402.5 billion.  Write a linear equation in slope-intercept form to model the amount (in billions of dollars) spent on recreation since 1990. *please look at it* (:

The slope of an equation is `rise over run'. In this case, the rise is the change in spending, the run is the number of years.

Now, the intercept depends. If you consider 1990 `0', then you'll have to make the intercept be $285.7 billion.

Hope that helps!
