Linear Inequalities & Testing Points

Front

Dashed line, because the inequality is strict (greater than).

What does a solid line indicate in a linear inequality?

Back

It indicates that the points on the line are included in the solution (less than or equal to, or greater than or equal to).

Front

What does a dashed line indicate in a linear inequality?

Back

It indicates that the points on the line are not included in the solution (strict inequalities).

Front

How do you determine if a point is a solution to an inequality?

Back

Substitute the point's coordinates into the inequality and check if the statement is true.

What is the general form of a linear inequality in two variables?

What does shading above the line in a graph of an inequality represent?

Back

It represents all the solutions that satisfy the inequality where y is greater than the line.
