A. She needs 16 quarter cups of milk.
B. Equation: 4 cups multiplied by 4(four quarter cups per cup) = 16 quarter cups
Hope this helps!!
The line of best fit helps you make predictions based upon ordered pairs that you have plotted. The independent variable is on the x axis. The dependent variable is on the y axis. You find the slope by plugging in the order pairs into a calculator which gives you the line of best fit.

Answer:

Step-by-step explanation:
I'm going to presume you want this linear equation in slope-intercept form, so start with:

Subtract
from both sides of the equation:

Subtract
from both sides of the equation:

Divide both sides of the equation by the coefficient of
, which is
:

Simplify:

Simplifying
5y + -2 = 4y + 7
Reorder the terms:
-2 + 5y = 4y + 7
Reorder the terms:
-2 + 5y = 7 + 4y
Solving
-2 + 5y = 7 + 4y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-4y' to each side of the equation.
-2 + 5y + -4y = 7 + 4y + -4y
Combine like terms: 5y + -4y = 1y
-2 + 1y = 7 + 4y + -4y
Combine like terms: 4y + -4y = 0
-2 + 1y = 7 + 0
-2 + 1y = 7
Add '2' to each side of the equation.
-2 + 2 + 1y = 7 + 2
Combine like terms: -2 + 2 = 0
0 + 1y = 7 + 2
1y = 7 + 2
Combine like terms: 7 + 2 = 9
1y = 9
Divide each side by '1'.
y = 9
Simplifying
y = 9
