| would you change > to < if you added negative 9 from both sides of an inequality | no
🗑
|
||||
| would you change > to < if you divided both sides of an inequality by nine? | no
🗑
|
||||
| would you change > to < if you divided both sides of an inequality by negative nine? | yes

| The vertical bar in set builder notation such as {t|t<17} is read as __ __ | such that
🗑

| After picking a test point that resulted in a false statement, which side of the line would you shade for an inequality in two variables? | You would color in the side of the boundary line that did NOT include the test point
🗑
|
||||
| After picking a test point that resulted in a TRUE statement, which side of the line would you shade for an inequality in two variables? | the half plane that included your test point
🗑
|
||||
| Since you get to decide which point to use for a test point for an inequality in two variables, what kind of points should you pick. | Any easy point that is not on the boundary line such as the origin or (1,1) etc.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
