What is the equation of the trend line?

A city manager made a scatter plot of the number of retail stores in the city over the years. A scatter plot had a trend line with an equation of y=11x+12, where y is the total number of retail stores and x is the number of years since 1990.

Use the equation to predict the number of retail stores in the city in 1997. (7 years later).
