This work is the result of an ‘Elective Undergraduate Research’ class at the Budapest Semesters in Mathematics in Spring 2014. After our proofs were completed, Brian Harbourne and Tomasz Szemberg have pointed out closely related work in the area (see Remark 2.8, Remark 2.9, and Remark 2.10, respectively, for more precise statements and references) for which we are grateful.
