Question 1087075: In 2004, in-state tuition at Stanford was $6,092. In 2013, in-state tuition was $9,992. If the cost of in-state tuition C is a linear function of time t, where t represents the number of years since 2004, write the linear function C(t).

In 2004, in-state tuition at Stanford was $6,092. In 2013, in-state tuition was $9,992. If the cost of in-state tuition C is a linear function of time t, where t represents the number of years since 2004, write the linear function C(t).
With t being time in 2004 (year 0), and tuition in 2004 being $6,092, we get the point: (0, 6,092).
With t being time (from 2004 to 2013), and tuition in 2013 being $9,992, we get the point: (9, 9,992).
