Answer 1

The answer would be C or Parrell sides.

Normal when you are using slope you are comparing lines to see how they would come together. Also all of the other answer you would have to use a different formula to get to the right answer.

The answer is c.

The slope formula can be used to prove a quadrilateral has parallel sides. This is made obvious when we remember that parallel lines have the same slopes.
