Point z on a coordinate grid is at (-1,3). if the point is reflected across the line y=-x, what are the coordinates of its image?

Recall the definition of a polynomial expression. find two polynomial expressions whose quotient, when simplified, is. use that division problem to determine whether polynomials are closed under division. then describe how theother three operations-addition, subtraction, and multiplication-are different from division of polynomials.
