Boundary Line: Solid vs. Dashed
Master Boundary Line: Solid vs. Dashed in Grade 10 math. ### Property When drawing the boundary line of a linear inequality, you must use specific formatting.
Key Concepts
Property When drawing the boundary line of a linear inequality, you must use specific formatting to show whether the line itself is part of the solution set:.
Dashed Line: Use for strictly "less than" ($<$) or "greater than" ($ $). Points sitting exactly on a dashed line are NOT solutions.
Solid Line: Use for "less than or equal to" ($\leq$) or "greater than or equal to" ($\geq$). Points sitting exactly on a solid line ARE solutions.
Common Questions
What is Boundary Line: Solid vs. Dashed?
### Property When drawing the boundary line of a linear inequality, you must use specific formatting to show whether the line itself is part of the solution set: Dashed Line: Use for strictly "less than" () or "greater than" (). Points sitting exactly on a dashed line are NOT solutions. Solid...
How do you apply Boundary Line: Solid vs. Dashed in practice?
### Examples The inequality requires a dashed boundary line because it is strictly "less than". A point sitting directly on the line, like , is not a solution because simplifies to , which is false. The inequality requires a solid boundary line because of the "or equal to" condition. Points on...
