Studies show that college students are taking longer to graduate from college. the coordinates show that less students are graduating in less than five years. In 1983, the coordinates representing a line of students graduating in less than 5 years were (0,58). Where x represents the year in 983 and y represents the percent graduating in less than five years. The next coordinate shows fourteen years later, in 1997, as follows; (14,53). Find an equation of the line given the coordinate.
