We also can't believe they are taking off a point because answer is an Ordered Pair

We are about to call SED 518-474-5900 about the rubric on #34. The rubric says to take one point off if they list the roots as an ordered pair. We disagree. Roots of a parabola are the x-intercepts. Why can?t they be written as an ordered pair? Especially since the question requires students to do the graph. What are other people?s thoughts on this?
