A city manager made a scatter plot of the number of retail stores in a certain city over the years. The 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. When Darryl and his family moved to the city in 1997, there were 133 retail stores in the city. Use the equation to predict what year Darryl's family moved to the city.
