You would have the points (1,20) and (8,4)
slope = (4-20)/(8-1) = -16/7 , (question could have been planned a bit better)
y - 20 = (-16/7)(x - 1)
clean it up if need be
15. At Generic High School, in the year 2001, there were 20 students per every computer. In 2008, there were 4 students per computer. Write two ordered pairs to represent the ratio of student to computer. (Let x equal the number of years since 2000.) Let x represent the time.
