## anonymous 3 years ago What is the slope of the line between (3, –4) and (–2, 1)?

1. anonymous

What is the change in y coordinates??

2. anonymous

3

3. anonymous

How??

4. anonymous

1--4= -3

5. anonymous

See, -(-) = + So, 1 - (-4) becomes 1 + 4 getting??

6. anonymous

5 but how

7. anonymous

-(-) becomes positive... Do you get that??

8. anonymous

ok so how to find the ans

9. anonymous

so you found y change = 5.. Now similarly tell me the change in x coordinates..

10. anonymous

-5

11. anonymous

Yes.. Now, $Slope = \frac{y \; change}{x \; change}$ Can you do it now??

12. anonymous

0

13. anonymous

How??

14. anonymous

$$Slope = \frac{5}{-5}$$ Is it 0???

15. anonymous

no u r wrong

16. anonymous

How??

17. anonymous

Aren't you getting the answer (-1) ???

18. anonymous

is in between -2 and 2

19. anonymous

See, the other formula of slope is: $Slope = \frac{y_2 - y_1}{x_2 - x_1}$

20. anonymous

$Slope = \frac{1 - (-4)}{-2-3} = \frac{5}{-5} = -1$

21. anonymous

Is -1 not between 2 and -2??

22. anonymous

$$-2, -1, 0 , 1, 2$$ It is between 2 and -2..
