Front

Select the graph for 5x + y ≤ -1.

Back

Graph D

Front

If the inequality symbol is > or ≥ you shade _________.

Back

above

Front

Which of the following inequalities matches the given graph? x ≥ -1, x ≤ -1, x > -1, x < -1

Back

x < -1

Front

What is a system of inequalities?

Back

A set of two or more inequalities with the same variables.

Front

What does it mean to shade above a line in a graph?

Back

It indicates that the solutions to the inequality are all the points above the line.

Front

What does it mean to shade below a line in a graph?

Back

It indicates that the solutions to the inequality are all the points below the line.

Front

What is the difference between a solid line and a dotted line in graphing inequalities?

Back

A solid line indicates that the points on the line are included in the solution (≥ or ≤), while a dotted line indicates they are not included (< or >).

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.
