If the statement is true, choose true. If it is false, replaced the underlined word(s) with the word(s) that will make the statement true.

A consistent system of equations has at least one solution.

• true

• false

• dependent

A system of independent equations has infinite solutions.

• true

• false

• dependent

An inconsistent system of independent equations has zero solutions.

• true

• false

• dependent

If the ordered pair is a solution to the system, choose solution. If it is not a solution to the system, put not a solution.

5x + 2y = 4 (2, - 3)

4x + y = 11

• solution

• not a solution

If the ordered pair is a solution to the system, choose solution. If it is not a solution to the system, put not a solution.

3x + 2y = 13 (1, 5)

4x - 3y = - 11

• solution

• not a solution

If the ordered pair is a solution to the system, choose solution. If it is not a solution to the system, put not a solution.

2x - 5y = - 22 (- 6, - 2)

3x - 2y = - 22

• solution

• not a solution
