When graphing the solutions to "OR" inequalities, The shading looks like___

• Shading that connects the 2 dots

• Shading that points away and never crosses.

• Shading that points toward each other and ALWAYS crosses

• Shading that points opposite, but sometimes crosses.

When graphing "AND" inequalites, shading looks like___

• Shading that always connects the 2 dots.
• Shading that always points away from each dot
• 2 shaded arrows pointing in same direction(both left)
• 2 shaded arrows pointing in same direction (both right)
