A Trapezoid needs to have one pair of sides parallel.
Two of the points already plotted have the same Y value ( 3)
So the 4th dot, should have the same Y value as the first dot, which is 1.
The 4th dot should be plotted at C (5,1)
A vertical line has the equation of x = a
If the vertical line goes through a certain point, as in this case, then the y value is irrelevant. It can be anything. It is the x value that is the one you need to use.
So the answer is x = 1. This equation has no slope that is defined.
1. x= 3/Y as a fraction btw
2. Same thing
