Answer:
55/16 cups or 3.4375 cups
Step-by-step explanation:
there are 5 dozens (12) in 60, so there are 2.5 2 dozens in 60, so you would multiply 1 3/8 by 2.5 to find how many cups are needed in 60 cupcakes because 1 3/8 cups is for 2 dozen cupcakes

If 
Then:

Sub in the coordinates given to you:

Now:

Move 1.5 to the other side of the equation and flip the sign.

Therefore,
.
Replace in the formula (y=mx+c):

There is your answer.
Answer:
I don't really understand but, the Y coordinate is always on the right side so therefore y= -2, and 1
(xYz)
The answer is 8, because 64÷8= 8!simple
