The number of conference attendees in 2002 was 690. In 2013, there was 502 attendees. Let y be the number of conference attendees in the year x, where x=0 represents the year 2002.
A.) Form a linear equation on slope- intercept form that models the decrease in the number of conference attendees in terms of x. [Hint the line must pass through the points (0,690) and (11,502)]
B.) Use this equation to predict the number of conference attendees in the year 2024.
C.) Explain what the slope for this line means in the context of the problem.
