What can be concluded about the graphed polygon?
On a coordinate plane, side a has points (negative 2, 4) and (5, 4), side b has points (5, 4) and (5, negative 3), side c has points (5, negative 3) and (negative 4, negative 3), and side d has points (negative 4, negative 3) and (negative 2, 4).
-The polygon is a rectangle.
-Adjacent sides of the polygon are perpendicular.
-Opposite sides of the polygon are parallel.
-The slope of side c is 0.
