it looks like you're missing some information :)

3. anonymous

i fixed it

4. UsukiDoll

cool :)

5. butterflydreamer

okayy. So, let's calculate the slope and see if she's correct :) Use this slope formula: |dw:1436357922980:dw|

6. butterflydreamer

so you're trying to solve: |dw:1436358176119:dw|

heeelloo? :O

sorry went togo get adrink

9. butterflydreamer

oh no problem :)!

10. anonymous

what is the answer

11. butterflydreamer

.... solve: $m= \frac{ -3 + 6 }{ 2+8 } = ?$

12. anonymous

-3/10

13. anonymous

=m

14. butterflydreamer

close! Remember that -3 + 6 = 6 - 3 = ?

15. anonymous

m-3/10

16. anonymous

m=

17. butterflydreamer

yes m = 3/10 So the student was correct right? :) They said that the slope was 3/10 as well

18. anonymous

thankyou again

19. butterflydreamer

no problem :))!
