Practice Graphing System of Inequalities

Front

What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables. The solution is the set of all points that satisfy all inequalities in the system.

What does it mean if a system of inequalities has an infinite number of solutions?

Back

It means that there are countless points that satisfy all inequalities in the system, typically represented by a shaded region on a graph.

What is the graphical representation of a solution to a system of inequalities?

Back

The graphical representation is typically a shaded region on a coordinate plane, indicating all the possible solutions that satisfy the inequalities.

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

Back

To determine if a point is a solution, substitute the point's coordinates into each inequality. If the point satisfies all inequalities, it is a solution.

What does the symbol '>' indicate in an inequality?

Back

'>' indicates that the value on the left is greater than the value on the right.

What does the symbol '≥' indicate in an inequality?

Back

'≥' indicates that the value on the left is greater than or equal to the value on the right.

What is the difference between '>' and '≥'?

Back

'>' does not include the boundary line, while '≥' includes the boundary line in the solution set.

How do you graph the inequality y < x + 1?

Back

To graph y < x + 1, draw the line y = x + 1 as a dashed line (not including the line) and shade below the line.

What is the significance of a dashed line in graphing inequalities?

Back

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

What is the significance of a solid line in graphing inequalities?

Back

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