Question

Students at Mills Middle School are required to work a certain number of community service hours. The table shows the numbers of additional hours several students worked beyond their required hours, as well as the total numbers of hours worked. Read the ordered pairs from this graph to make a table. Write an equation that expresses the total hours in terms of the additional hours.

Answer 1

I found the table and graph. see attachment.
x is the additional hours
y is the total number of hours 

x           y
0        20
5        25
10      30
15      35
20      40

The equation would be:  y = 20 + x  

20 represents the total number of hours the students are required to work as community service.
