WU Graphing Systems of Inequalities Review

Front

What does the graph of y ≥ x - 3 represent in terms of shading?

Back

The graph is shaded Over / Above the line.

Front

Which point is a solution to the inequality system? (0, 6), (-3, 4), (1, 0), (-4, 3)

Back

(1, 0) is a solution.

Front

Is the point (-2, 4) a solution to the system of inequalities?

Back

Yes, (-2, 4) is a solution.

Front

What type of line is used for inequalities with > or

Back

A dashed line is used.

Front

Will the line be solid for the inequality 5 ≥ x?

Back

Yes, the line will be solid.

Front

What does a solid line indicate in graphing inequalities?

Back

A solid line indicates that the points on the line are included in the solution.

Front

What does a dashed line indicate in graphing inequalities?

Back

A dashed line indicates that the points on the line are not included in the solution.

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality; if it satisfies all, it is a solution.

Front

What is the graphical representation of the inequality y < 2x + 1?

Back

The area below the line y = 2x + 1 is shaded.

Front

What is the significance of the boundary line in a system of inequalities?

Back

The boundary line separates the solution region from the non-solution region.
