PLEASE HELP ME!! :((( How do you prove each of the following properties of a parallelogram?
o Opposite sides of a parallelogram are congruent.

o Opposite angles of a parallelogram are congruent.

o The diagonals of a parallelogram bisect each other.

o If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a
parallelogram.

o Rectangles are special parallelograms with congruent diagonals.

i believe it's a.

i'm not sure on this one, most likely correct.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
