Answer
y = 2x
Explanation
The first thing is to find the gradient of the line.
Gradient = Δy/Δx
= (4--2)/(2--1)
= 6/3
= 2
Now a general point (x, y) and one of thegiven points.
(y - 4)/(x - 2) = 2
y - 4 = 2(x - 2)
y = 2x - 4 + 4
y = 2x + 0
y = 2x
2/3=3/x
2x=9
x=4.5
z=2+4.5
z=6.5
2/y=y/6.5
y^2=13
y= 3.61
Profit = paid - supplies
Plug in the given values. We are finding out how much money he needs per room, if he is doing 4 rooms, and subtracting the supplies: 300 = 4n - 4*32.50
Simplify: 300 = 4n - 130
Add 130 to each side. 430 = 4n
Divide by 4 on each side: 107.50= n
300 = 4(107.50) - 130? True
This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.

Answer:
Finding the missing number is fairly simple and can be done in a few short steps. I will show you using the 21 / __ fraction.
First, divide the included number by its corresponding number in the original fraction.
21 ÷ 3 = 7
To find what the denominator of this would be, multiply 4 by 7.
4 * 7 = 28
The fraction would be 21 / 28.
This works with both numerators and denominators. If you need more of the answers just ask in the comments.
