Find the slope of a line passing through the given points.

2. jim_thompson5910

what points? you just posted the slope formula

3. itsjustme_lol

4. jim_thompson5910

m = (y2-y1)/(x2-x1) m = (-3-2)/(1-(-4)) m = (-3-2)/(1+4) I'll let you finish

7. jim_thompson5910

cinar is just pointing how how x1 is -4, y1 is 2, etc etc

8. jim_thompson5910

and my last step is not the answer

9. jim_thompson5910

you have to keep going

10. itsjustme_lol

ohhhh. ok

11. ByteMe

what's -3-2 = ??? 1+4 = ???

12. itsjustme_lol

-3-2=-5? 1+4=5? so m=5,5?

13. jim_thompson5910

you divide the two though and one of those is negative

14. jim_thompson5910

which means your final slope is negative

15. itsjustme_lol

why would I divide the 2?

16. jim_thompson5910

because it's rise/run

17. jim_thompson5910

rise is the change in y run is the change in x

18. ByteMe

jim did not say to divide by 2.... he said divide the two....

19. jim_thompson5910

i think he meant "divide the two numbers" not by "divide by 2"

20. ByteMe

oh.. yur right... :)

21. itsjustme_lol

so its m=-1?

22. jim_thompson5910

yep

23. itsjustme_lol

thanks
