Y=2x +4 is non proportional because b does not equal 0
The b in the equation is 4
As long as the y intercept is not more or less than 0, than it will be proportional

Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
It would be 1.5 per foot, but how many feet do they want
Answer:
Twice a number increased by five - 2x + 5
Five decreased by twice a number- 5 - 2x
Twice the difference of a number and five- 2(x - 5)
Twice the sum of a number and five= 2(x + 5)
Five subtracted from twice a number= 2x - 5
Twice a number, less five= 2x - 5
