Let the function be y = ax + c.
For (-1,8), 8 = a(-1) + c → 8 = - a + c
For (5,6), 6 = a(5) + c → 6 = 5a + c
Subtract one from abother,
2 = - 6a => - 1/3 = a
Hence, 8 = - 1/3 + c → 23/3 = c
Relation is:
y = (-1/3)x + (23/3)
3y = - x + 23
3y = 23 - x
Celia is making cookies for her neighborhood. She plans to make 9 batches of 13 cookies, but she makes more cookie dough than she planned to and adds 6 cookies to each batch. After they bake, she takes them out of the oven and takes 7 cookies from each tray to keep for herself. How many cookies will be left to distribute among her neighbors?

Answer:
A) 

Step-by-step explanation:
When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:

Use inverse operations to solve this equation,



The circumference of a circle is all around the circle
The diameter is a line that crosses straight across a circle
And the radius is half the diameter :)
