(1). A city's population has been growing linearly. In 2008, the population was 28,200. By 2012, the population was 36,800. Assume the trend continues. That is, assume that the relationship between the population and the years past 2008 is linear. a) Write an equation describing this relationship. b) Use your equation to predict the population in 2014. c) Find an equation of the line that passes through the point (-4, 1) and is perpendicular to the line 5x - 3y + 4 = 0. Write your answer in slope-intercept form. 2 d) Use completing the square to find the center and radius of the circle with the equation: x + 1 = 0 + y² + 8x - 2y (1).
