Please help me out!!!!

Reading the graph from the problem, we get the following answers for the table.
Time Savings
10 100
20 200
25 250
Second, lets calculate saving/time to find the ratio between the two, which will be our k. 100/10 = 10.
Therefore, our equation is y = 10x.
The points are (10,100), (20,200), and (25,250) so the table is
Time 10 20 25
Savings 100 200 250
The next question is presumably what is the equation, which is clearly
[tex]y = 10 x[/tex]
