There's no graph and I already cant do slope....

y=1/2x+1

Step-by-step explanation:

you need x1 y1 and x2 y2

In your problem x1 is -8

In your problem y1 is -3

In your problem x2 is 10

In your problem y2 is 6

you need to do y2-y1/x2-x1 so basically

6-(-3)/10-(-8)

which is 9/18 or 1/2x

6. You have 21 cookies and you want to give 3/7 to your friend. How many do you give to your friend?
21 * 3/7 = 9. You would give 9 cookies.
7. 1/2 / 5 = 1/10 - siblings
   1/4 / 2 =  1/8  - friends
A single friend got more because 1/8 is greater than 1/10.
Hope this helps!
