First, subtract 9 from both sides of the inequality:
6x > 57 - 9
6x > 48
Next, divide both sides of the inequality by 6 to solve for x:
x > 48/6
x > 8
The solution to the inequality is x > 8.
Looking at the options, the graph that shows the solution is:
A number line is shown ranging from negative 2 to 18 with numbers listed in unit increments. An open point is plotted on the number line at 8. A rightward arrow is marked on the number line that originates at the open point and goes beyond 18.
