Algebra Chapter 6 Test REVIEW Short Answer 1. Find a solution to the following system of equations.

2. What is the solution of the system of equations?

−5x + y = −5 −4x + 2y = 2

y = 3x + 7 y=x–9

Graph each system. Tell whether the system has no solution, one solution, or infinitely many solutions. 3. y = 5x – 4 y = 5x – 5

4. y = x + 4 y–4=x

ID: A 5. y = 2x – 3 y = –x + 3

6. The length of a rectangle is 2 cm more than four times the width. If the perimeter of the rectangle is 84 cm, what are its dimensions?

Solve the system of equations using substitution. 7. y = 2x + 3 y = 3x + 1

9. 3x + 2y = 7 y = –3x + 11

8. y = 4x + 6 y = 2x

ID: A Solve the system using elimination. 10. 3x + 3y = –9 3x – 3y = 21

11. x + 2y = –6 3x + 8y = –20

12. By what number should you multiply the first equation to solve using elimination? –3x – 2y = 2 –9x + 3y = 24

Graph the inequality. 13. y < 4x − 2

14. 4x + 6y ≥ 10

3

ID: A 15. 3x − 7y < −21

18. Write the inequality that is graphed.

16. y > −5x + 3

19. Solve the system of inequalities by graphing. y ≤ x+4 2x + y ≤ −4

17. Write the following inequality in slope-intercept form. 5x − 5y ≥ 70
