On graph paper, plot the points $\left(2,3\right), \left(4,7\right)$, and $\left(8,7\right)$. .

1. Name a point that you could plot so that the four points form the vertices of a parallelogram.

   Hint:

   Remember, coordinate points are written in the form $\left(x, y\right)$.

   Hint (a):

   Remember, a parallelogram is a quadrilateral with both pairs of opposite sides parallel and of equal length.

2. Name a point that you could plot so that the four points form the vertices of a trapezoid.

   Hint (b):

   A trapezoid is a quadrilateral with at least one pair of parallel sides.
