Step-by-step explanation:
The change in temperature will be the original temperature plus or minus x, the change between a temp and b temp, to equal what the temperature is now.
 
        
                    
             
        
        
        
Step-by-step explanation:
The formula the amusement parc use is  100y-39000=55(x-800)
The slope intercept form of a function is wriiten generally as: 
y = mx+c 
- m is a slope 
- c is a constant and represents the y-intercept 
- x is a variable 
- y is the input of the function 
Let's rewrite our equation in the precedent form 
- 100y-39000 = 55(x-800)
- 100y -39000 = 55x-44000    add 39000 in both sides
- 100y-39000+39000 = 55x-44000+39000
- 100y = 55x-5000            divide both sides by 100
- y = 0.55x-50
The slope intercept form of this equation is:
y= 0.55x-50
