Writing Linear Equations In 1993, the cost of tuition at a large Midwestern university was $120 per credit hour. In 2000, tuition had
risen to $183 per credit hour.
Determine a linear equation to represent the cost, C, of tuition as a function of x, the number of years
since 1990. (Assuming the cost increases by the same amount each year.)
Linear Equation:
In the year 2002, tuition will be $
per credit hour
In the year
