$f\left( x \right)=mx+b$
Work Step by Step
In the provided graph between Dormitory charges for public two-year colleges and school year, it is observed that the data points rise continuously. The graph does not appear to represent a quadratic function that opens upward or downward.
Thus, the linear function $f\left( x \right)=mx+b$ can be used to model the data.
