[1] Appropriate work is shown, but one computational or simplification error is made, such as
not combining like terms.
[1] Appropriate work is shown, but one conceptual error is made, such as multiplying exponents
rather than adding exponents when distributing.

[0] Completely incorrect, irrelevant, or incoherent or is a correct response that was obtained by
an obviously incorrect procedure.

[2] –3, –2, and 2, and correct work is shown.
[1] Appropriate work is shown, but one computational error is made, such as factoring x
– 4
2
into x + 1 and x – 4, but three zeros are stated.
[1] Appropriate work is shown, but one conceptual error is made, such as obtaining a single zero
from the x

[2] A correct system of equations is written, such as 1.25x + 2.75y = 55 and x + y = 26, and
the numbers of songs is correctly stated as 11 and the number of movies is correctly stated
as 15, with correct algebraic work or correct graphical work shown.
[1] Appropriate work is shown, but one computational or graphing error is made.
[1] Appropriate work is shown, but one conceptual error is made, such as stating there are 11
movies and 15 songs.
[1] A correct system is written and 11 songs and 15 movies stated, but with no work shown,
or using a method other than algebraic or graphical, such as guessing and checking.
[1] A correct system is written but no further correct work is shown.
[0] Completely incorrect, irrelevant, or incoherent or is a correct response that was obtained by
an obviously incorrect procedure.
