37 Score Explanation
4 Secant points of intersection are (0, 5) and (2, 4), and an appropriate explanation is
given.
3 Secant is given, but graph is incorrect.
2 Graph is shown, but secant is not given.
1 Secant is given, but graph is not shown.
0 A zero response is completely incorrect, irrelevant, or incoherent or is a correct response
that was obtained by an obviously incorrect procedure.
Part IV
For each question, use the specific criteria to award a maximum of 6 credits.
38 Score Explanation
6 Any appropriate method is used to prove that ABCD is a parallelogram, but not a rectangle.
For example: showing that the diagonals bisect each other but are not congruent,
or showing that no consecutive sides have negative reciprocal slopes.
5 An appropriate method is used, but a single computational error is made.
4 An appropriate method is used, but two computational errors are made.
3 An appropriate method is used to prove that ABCD is a parallelogram but does not
show that it is not a rectangle.
2 An appropriate method is used to prove that ABCD is a parallelogram, but more than
two computational errors are made and student does not show that it is not a rectangle.
1 An appropriate method is used, but ABCD is not shown to be a parallelogram, and
multiple computational errors are made.
0 A zero response is completely incorrect, irrelevant, or incoherent or is a correct response
that was obtained by an obviously incorrect procedure.
