<span>A geometric plane is two-dimensional. Standing at one point in the plane and picking two directions to travel which are not opposites of one another, any direction of travel on the plane can be obtained by composing these two directions. Since it is two directions, the plane is two-dimensional.
There is a way of describing this also using algebra. The general equation for a plane is ax + by + c = 0. For example, when a = 2, b = 3, and c = 4, the equation 2x + 3y = 4 is that of a plane. Since there are two variables here, x and y, the plane is two-dimensional.</span>
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.
