What is a system of inequalities?

Back

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

Front

What does a solid line represent in graphing inequalities?

Back

It represents that the points on the line are included in the solution set (≤ or ≥).

Front

What does a dotted line represent in graphing inequalities?

Back

It indicates that the points on the line are not included in the solution set (< 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.

Front

What is the graphical representation of the inequality y < 2x + 3?
