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.

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?


Thanks,
