## dmezzullo Group Title Which of the following is the slope between the two points (-3, 1) and (3, -6)? six sevenths -six sevenths seven sixths -seven sixths one year ago one year ago

1. hartnn Group Title

The slope of the line through points (x1,y1) and (x2,y2) is given by : $$\huge m=\frac{y_1-y_2}{x_1-x_2}$$ now,just put the values and find m.

2. ZeHanz Group Title

Given the points (x1,y1) and (x2,y2), the slope is (y2-y1)/(x2-x1). Go and do the math. It works. Every time!

3. dmezzullo Group Title

Is it possible to have it in simple terms lol?

4. hartnn Group Title

you first take the difference of y values, then take difference of x values, then just divide them...

5. hartnn Group Title

so, whats the difference of y values?

6. hartnn Group Title

do u have difficulty figuring out y values ?

7. dmezzullo Group Title

yes

8. ZeHanz Group Title

Should be as difficult as the x values ;)

9. dmezzullo Group Title

So divide -3 by 3 and 1 by 6?

10. hartnn Group Title

|dw:1359650325553:dw| now ?

11. hartnn Group Title

no...not divide....subtract.

12. dmezzullo Group Title

so divide -3 by y and +3 by x?

13. hartnn Group Title

no...y values are 1 and -6, right ? so, 1-(-6) =... ?

14. ZeHanz Group Title

There is another way. Imagine you are at the leftmost point, (-3,1). Now, to get to the rightmost point, (3,-6) you have to go 6 steps to the right, and 7 steps down (just count), so a vertical move of -7. Now ask yourself: what is the vertical move if I would go 1 (one) step to the right along the line? That is its slope.

15. dmezzullo Group Title

OHHHHH WOULD THE ANSWER BE 6/7 THEN?

16. ZeHanz Group Title

No, it would be negative, because you have to go down if you go from the leftmost to the rightmost point. Further, while you go 6 steps to the right, you go 7 steps down, so that is more than 1 unit per step...

17. dmezzullo Group Title

OHHH i see now, i was thinkin go up not down.

18. dmezzullo Group Title

tyvm

19. ZeHanz Group Title

20. dmezzullo Group Title

-6/7

21. ZeHanz Group Title

THe minus sign is good. Now think about 6/7: it is smaller than 1. That is not good, because if you go 1 unit to the right, you go more than 1 unit down...

22. dmezzullo Group Title

wait so would it be -7/6 then?

23. ZeHanz Group Title

Yes! Try to remember this way of doing it!
