## kenyababii123 3 years ago Which of the following is the slope between the points (0, -10) and (-4, 0)? a. 2/5 b.-2/5 c.-5/2 d.5/2

1. zordoloom

Do you know how to find the slope between 2 points?

2. hartnn

know the formula to find slope ?

3. hartnn

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.

4. hartnn

so what slope did u get ?

5. kenyababii123

I don't understand slope can you explain how i am supposed to set up the equation and then i could solve it

6. hartnn

First point , (0,-10) compare it with (x1,y1) u get x1=0, y1=-10 in same way find x2 and y2 and put all these 4 values in the formula i gave you to find slope =m

7. kenyababii123

so would it be 0,-4/-10,0 for the equation?

8. hartnn

the numerator has y-values

9. hartnn

so in the numerator, its -10-0 got this ? what will be in the denominator then ?

10. kenyababii123

the denominator would be -4-0 ?

11. kenyababii123

i meant 0-4 ?

12. hartnn

u missed a - *minus* sign $$\huge 0-(-4)= 0+4=?$$

13. hartnn

one minus sign comes from formula and one from the fact that the co-ordinate itself is negative , its -4

14. kenyababii123

so would the equation be -10-0/0+4

15. hartnn

yes! correct :) m=(-10-0)/(0+4)

16. hartnn

so m= ?

17. kenyababii123

hold on im working out the problem now

18. kenyababii123

so the answer would be -5/2

19. hartnn

yes, that is absolutely correct! good :)

20. kenyababii123

ok thank you so much :)

welcome ^_^
