## tw101 one year ago List two coordinates of two locations that, when connected, create a positive slope. Prove they are positive by putting them into the slope formula. List two coordinates that, when connected, create a negative slope. Put into slope formula. my positive points are (2,5) (12,19) my negative points are (12,19) (21,5) (Theyre the two sides of a triangle. Im a little confused on how to put them into slope form.

2. tw101

so would it be 5-19 over 1-12?

3. LynFran

|dw:1436212692108:dw|

4. tw101

wait where did you get the 2?

5. LynFran

thats the points you give...(2,5)..(12,19)...your positive points

7. tw101

Oh right im sorry I got mixed up youre right, my apologies.

8. tw101

so then it would be 14/10 right?

9. LynFran

look back at this |dw:1436213104684:dw|

10. tw101

right. 19-5=14 and 12-2=10

11. tw101

simplified its 7/5 right?

12. LynFran

correct

13. tw101

okay so the slope is 7/5 and the y intercept is 11/5 and then the formula is y=mx+b so it would be y=(7/5)x+11/5?

14. LynFran

|dw:1436213507075:dw|

15. tw101

okay so would that be the only thing I would have to do? or is there another step?

16. LynFran

thats it for the positive slope part...your have to to the negative slope part..can you find the slope and its equation(for the negative points)...

17. tw101

ill try:) one second.

18. tw101

m=-14/9 y-int=113/3 @LynFran

19. LynFran

correct

20. tw101

okay thank you so much

21. LynFran

welcome
