<h3>Answer:</h3>
<h3>Explanation:</h3>
You want the graph to cover the period from now until 10 months from now (m=10). In that period, Benji will have read 2.5×10 = 25 more books than he has currently. That will bring his total to 5+25 = 30 for the year.
The graph must display numbers on the B axis that go from 0 to 30, and must display numbers on the m axis that go from 0 to 10 in order to cover the period of time described by the problem.
According to your statement, it's expression would be:
9 + 2x
So, your correct answer is 9 + 2x
