8. Definitions: origin

9. Definitions: quadrants

10. Definitions: x-coordinate

11. Definitions: y-coordinate

12. Definitions: solution

13. Definitions: graph

14. Definitions: y-intercept

15. Definitions: x-intercept

16. Definitions: linear equation

17. Definitions: general form of a linear equation

18. Sketch the graph of 3x + 2y = 18.

19. Determine where the lines intersect. 2x + 5y = 10 3x + 4y = 12

20. When two linear equations have no common solution, their graph are ???

21. When two linear equations have infinitely many solutions, their graph are ???

22. Solve. Then graph the solutions. 3x - y = 9 7x - 5y = 25

23. Distance Formula:

24. Midpoint Formula:

25. If A = (-1, 9) and B = (4, -3), find the length of AB and the coordinates of the midpoint of AB.
