To find the value for x that the 8th grade class work for the same number of hours and earn the same amount of money is to look at the point where both lines intersect.
On the graph, the line intertects at (5, 35).
x = 5
y = 35
Therefore, it took 5 hours for the 8th grade class to work the same amount of hours to earn the same amount of money.
Best of Luck!
