Textbook Problem

Let *f* and *g* be linear functions with equations *f*(*x*) = *m*_{1}*x* + *b*_{1}*,* and *g*(*x*) = *m*_{2}*x* + *b*_{2}*.* Is *f* ◦ *g* also a linear function? If so, what is the slope of its graph?

To determine

**To check:** Whether
*f* and *g* are linear; find the slope of the graph

Explanation

**Given:**

The linear functions are

**Calculation:**
