3. cupcake_queen

i got 0/6

4. moser90

right but the problem is undefined

5. moser90

do you see why?

I responded here(: Let me know if it helped! http://openstudy.com/study#/updates/50578021e4b02986d3714d23

7. cupcake_queen

so if it results with 0 over something its undefined

8. jazy

If it results 0 over something the slope is 0. ex: rise/run .0 rise means it does not rise at all. Its a horizontal line

9. jazy

The equation would be y =

10. cupcake_queen

0

11. jazy

0 is the slope.... there is no slope. Where does the line cross the y-axis? y = the y-intercept

12. cupcake_queen

so its undefined

13. cupcake_queen

14. jazy

No it'd be y = 1 because the line crosses the y-axis at 1.|dw:1347913646315:dw|

15. cupcake_queen

i dont have to graph it

16. jazy

That was to help explain what i meant. The equation would be y = 1

17. cupcake_queen

why?

18. jazy

y = mx + b m = slope b = y -intercept (where the line crosses the y-axis) slope = 0 and 1 is the y-intercept: y = 0x + 1 0x = 0 y = 1 That help?

19. cupcake_queen

im not using that formula

20. jazy

Wait all you need is to find the slope of these two pairs. (5,1),(11,1), right? Then the slope is 0.

21. cupcake_queen

ya

22. cupcake_queen

so its not undefined

23. jazy

Just remember: Horizontal line... Slope = 0 Vertical line... Slope = undefined
