A graph is shown in the xy-plane. The values on the x-axis ranges from negative 8 to 8 in increments of 2 and the values on the y-axis ranges from negative 8 to 8 in increments of 2. Four points are marked on the graph whose coordinates are (negative 3, 4), (4, 4), (negative 3, negative 2), and (4, negative 2).

Determine the height of the quadrilateral.
Determine the length of the quadrilateral.
Gina said the points formed a square. Is she correct? Explain your reasoning.
