Student Name:______

A.G.6 / 2 / 1 / 0
Show Work
(Weight: .50) / The student either list the slope and y intercept of each linear inequality
OR
List the xy table from -2 to 2 if using the graphing calculator / The student shows part of the work. Either the slope or the y intercept is listed for each of the linear inequalities
OR
Part of the xy table is listed, but not from -2 to 2
OR
the work is listed but it is incorrect / The student does not list the slope, y intercept, and/or a xy table.
Shade
(Weight: .50) / The student shades his or her coordinate graph, which symbolizes where all of the solutions are. He or she shades above the linear inequality when using the greater than symbol or below the when using the less than symbol linear inequality / The student shades the graph, but does not shade in the correct way. / The student does not shade the graph at all.
Type of line
(Weight: .50) / The student draws a dashed line to represent a non-equal to linear inequality or a solid line to represent an equal to linear inequality. / The student does not use the proper line to graph the linear inequality. / The student does not graph the inequality.
Label
(Weight: .50) / The student clearly and properly labels the line with the original linear inequality. / The student does not label the line with the original linear inequality. / There is not label at all.
A.A.24 / 2 / 1 / 0
Show work
(Weight: 1) / The student shows every step in solving each linear inequality with one variable. He or she adds or subtracts first and then multiplies or divides. / The student shows some work in solving each linear inequality with one variable. / The student shows no work when solving each linear inequality with one variable.
Flip sign
(Weight: .50) / The student flips the inequality symbol when multiplying and/or dividing by a negative and ONLY then! / The student does not flip the inequality symbol or does at the inappropriate time.
Graph using a number line
(Weight: .50) / The student uses an open circle when graphing a linear inequality in one variable that is non-equal to and a closed circle when graphing a linear inequality in one variable that is equal to.
AND
The student draws a line that properly shows the solutions of the inequality. / The student uses a circle and draws a line to indicate the solution, but does not do it in the proper way. / The student does not draw a circle or a line to indicate the solution.
