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).

Several schools reported the number of students who received a flu vaccine in a year and the number of cases of the flu amongst their students that year. A scatter plot was made with a trend line that had an equation of y=-\frac{1}{4}x+85. Use the equation to predict the number of cases of the flu that would occur if 300 students received he flu vaccine.

A scatter plot was created to show the length of a person's vacation and the weight of the suitcase they packed. The equation of the trend line is y=5x+15, where x represents the length of the trip.

Use the equation to predict the weight of a suitcase for someone taking a 9-day trip.
