In the question, there are certain information's that are of immense importance in regards to finding the answer. The first information is that Jose Rivera had purchased 7 textbooks for his classes at River Run Community College. The price that Jose Rivera had to pay was $208.55. The average cost per textbook needs to be found.
The cost of 7 textbooks purchased by Jose Rivera = 208.55 dollars
Then
The cost of 1 textbook purchased by Jose Rivera = (208.55/7) dollars
                                                                               = 29.79 dollars
The average cost of a textbook purchased by Jose Rivera rounded to the nearest cent is 29.80 dollars. 
        
             
        
        
        
The Y-intercept is found when X is equal to 0.
 In the table, when X is 0, f(x) is 1.
 On the graph, when X is 0 the line crosses at Y = 1.
This means that they are equal.
 The answer would be equal to.
