A1-U4.5a Lesson Check: Systems of Linear Inequalities

Front

What type of line is used when graphing inequalities with the symbols ≤ or ≥?

Back

A solid line.

Front

Which point is a solution to the system of inequalities: (0, -2), (-3, 0), (-3, 2), (1, 1)?

Back

(1, 1)

Front

If the inequality symbol is > or \ge, which direction do you shade on the graph?

Back

Above.

Front

Which point is NOT a solution to the system of inequalities: (0, 0), (3, -2), (3, -4), (4, -4)?

Back

(0, 0)

Front

Which point is a solution to the system of inequalities: (0, 0), (-3, 0), (2, -5), (3, -1)?

Back

(2, -5)

Front

What is a system of linear inequalities?

Back

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

Front

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

Back

Substitute the point into each inequality and check if all inequalities are satisfied.

Front

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

Back

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

Front

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

Back

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

Front

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

Back

The area below the line y = 2x + 3 is shaded.
