Unit 2 Lesson 20-24 (Inequality solutions) #2

Front

What does a dashed line represent in an inequality graph?

Back

A dashed line indicates that the points on the line are not included in the solution set (i.e., the inequality is strict, such as > or <).

Front

What does a solid line represent in an inequality graph?

Back

A solid line indicates that the points on the line are included in the solution set (i.e., the inequality is non-strict, such as ≥ or ≤).

Front

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

Back

Substitute the coordinates of the point into the inequality. If the inequality holds true, then the point is a solution.

Front

Back

The inequality represented is that y is greater than the value of the linear expression on the right side.

Front

Back

The inequality represented is that y is greater than or equal to the value of the linear expression on the right side.

Front

What does it mean if a point lies above a dashed line in a graph?

Back

It means that the point is a solution to the inequality represented by that dashed line.

Front

What does it mean if a point lies below a solid line in a graph?

Back

It means that the point is not a solution to the inequality represented by that solid line.
