Well considering that you did not give any option to choose from I cant give you an answer, but the graph should look like a line with the y-intercept at 9 and the x-intercept at 3, and all of the region to the right of the line shaded
A^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 + 81 = 324
a^2 = 243
a = 15.589 = 15.6 feet is the angle the ladder is at :)
