What is the solution to the system of inequalities represented graphically?

Back

(Graphical representation of the solution set)

Front

Which equation corresponds to the graph: y ≤ -3/4 x + 3, y ≥ -3/4 x + 3, y < -3/4 x + 3, y > -3/4 x + 3?

Back

Front

What does a solid line represent in graphing inequalities?

Back

It indicates that the points on the line are included in the solution set.

Front

What does a dashed line represent in graphing inequalities?

Back

It indicates that the points on the line are NOT included in the solution set.

Front

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

Back

Substitute the point into the inequality and check if it holds true.

Front

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

Back

A dashed line for y = 2x + 1, shading below the line.

Front

What is the difference between a system of inequalities and a single inequality?

Back

A system of inequalities consists of two or more inequalities that are solved together.
