Answer : option C
An electrician is hired to install a ceiling fan. She estimates that the installation will take no more than 45 minutes if the house is up to building code. The installation will take 45 minutes or less than 45 minutes. So we put a solid circle at 45 and shade to the left.
If the house is not up to building code, she estimates that the installation will take longer than 120 minutes. The installation will take more than 120 minutes. So we put a hollow circle at 120 and shade to the right.
So third diagram is correct.
the x intercept is (12,0) and the y is (0,-8)
