### March 1 Graphing And Slope

1. 1. GRAPHING!
2. 2. Consider the following y=x What happens to y as x increases? by how much?
3. 3. OK, consider this y = 2x What happens to y as x increases? by how much?
4. 4. How about this? y = 5x What happens to y as x increases? by how much?
5. 5. from back of the class Marc: this is algebra, what does this have to do with graphing?? Jerome: I don't know Ken: I like cheese
6. 6. Describe this line
7. 7. Describe this line
8. 8. Describe this line
9. 9. Jerissa: where is he going with this? Tricia: huh? Chastity: Khoa you stink!
10. 10. lets go back and look at the equations y=x here are some values of y at different values of x x 1 2 3 0 -1 -2 -3 y 1 2 3 0 -1 -2 -3
11. 11. lets go back and look at the equations y = 2x here are some values of y at different values of x x 1 2 3 0 -1 -2 -3 y 2 4 6 0 -2 -4 -6
12. 12. lets go back and look at the equations y = 5x here are some values of y at different values of x x 1 2 3 0 -1 -2 -3 y 5 10 15 0 -5 -10 -15
13. 13. Cedric: I think I see where he is going here, I think I could graph those values! Phong: ZZZZZZZZZ
14. 14. y=x x 1 2 3 0 -1 -2 -3 y 1 2 3 0 -1 -2 -3
15. 15. y = 2x x 1 2 3 0 -1 -2 -3 y 2 4 6 0 -2 -4 -6
16. 16. y = 5x x 1 2 3 0 -1 -2 -3 y 5 10 30 0 -5 -10 -30
17. 17. y= x So what happens to the line when this number gets bigger? What happens when it gets smaller?
18. 18. Let's use a letter to represent this value. Let's us m. y = mx Let's give m a name, we can call it SLOPE
19. 19. What happens to a line as m gets smaller? What if it was so small it was negative?!
20. 20. Graph y = -1x
