We understand what is technically mathematically correct, but the issue is, is it worth taking 33% of the credit off on this question because of that concept on an Algebra 1 exam?

Because there is no y in the equation they are asked to solve, the answers should not be in ordered pairs.
We were grumpy about a similar question a few years ago, but there is no y in the quadratic equation. So mathematically the answer should not be an ordered pair.
SED is consistent on their answer from years past.

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?
