    What is slope intercept form?

     

    • Ax+By=C 
    • y=mx+b 

  2. 00:01:12 

    How would I write the y-intercept as an ordered pair?

     

    • (0, 4) 
    • (4,0) 

  3. 00:01:47 

    Will be...

     

    • -2 

  4. 00:02:14 

    Which way will I go?

  5. 00:04:07 

    How many lines on one graph?

     


  6. 00:04:59 

    Is...

     

    • (5, 0) 
    • (0, 5) 

  7. 00:05:19 

    How will I move?

     

    • rise 2 
    • Run 2 
    • run 1 
    • run 0 
    • rise 1 

  8. 00:06:42 

    And then...

     

    • rise 4 
    • rise -4 
    • run -4 
    • run 1 

  9. 00:07:43 

    Extend the graph and see where they intersect before you move on.

    Where do they intersect?

     

    • (1, 3) 
    • (-1, 3) 
    • (3, -1) 

  11. 00:09:07 

    What is the solution?

     

    • (-1, 3) 
    • (1, -3) 
    • (3, -1) 

  12. 00:09:29 

    What do you think it means?

  13. 00:10:06 

    Solve it for y. You get...

     


  14. 00:10:27 

    Solve it for y. You get...

     

    • -3 
    • -5 

  15. 00:12:10 

    Write the problem down.

    What letter stands for extra points?

     


  17. 00:13:08 

    What stands for field goals?

     


  18. 00:13:45 

    How many?

     


  19. 00:13:47 

    How many?

     


  20. 00:15:13 

    What is the slope and y-intercept?

     

    • slope is -1 
    • y-intercept is 8 
    • slope is 8 
    • y-intercept is -1 

  21. 00:15:38 

    How do you get rid of the 3?

     

    • multiply by 3 
    • divide by 3 
    • subtract 3 

  22. 00:16:23 

    What is the slope and y-intercept?

     

    • slope is -1/3 
    • y-intercept is 4 
    • slope is 4 
    • y-intercept is -1/3 

  23. 00:16:52 

    Just watch, don't graph.

  24. 00:18:44 

    Do both the 1 and the 3 get the negative sign?

     

    • Yes 
    • No 

  25. 00:19:20 

    Ordered pair is...

     

    • (6, 2) 
    • (2, 6) 

  26. 00:20:05 

    So how many extra points did he make?

    What is the solution to a system of equations?

     

    • where one line crosses the y axis 
    • where the two lines intersect 
    • always at the same point no matter what problem
