I can not see the question it is blurry
As we know Conversion from fahrenheit to celsius is

We can write it also as

F as y and C as x then we can write it as
Answer:
x = 11
Step-by-step explanation:
The angles in a square are right , that is 90°
The diagonals bisect the angles , then
6x - 21 = 45 ( add 21 to both sides )
6x = 66 ( divide both sides by 6 )
x = 11
I think the answer is 80 fluid ounces
Let's start with the x coordinates.
-8 is on the left, and -4 to the right, so that will help organize this.
the line goes from -8,-9 to -4,-8. it moved 4 over the x axis and rose 1 over the y axis.
rise/run so 1/4 is the slope.
y=(1/4)x - 7
