(1/2)x+b=y because the equation that given the slope is 1/2 if you leave y alone and take the x’s number 
put the point now , 4+b=3 so b is -1 
the equation is (1/2)x-1=y
        
             
        
        
        
Answer:
The function rule for x is +1 and y is -5
Step-by-step explanation:
The function rule is basically the change for the set of numbers, like how x = 1, 2, 3, the function rule is +1, it's just the rate of change for the set of numbers.

Answer:
The maximum distance is 17.5 miles
No she can't make to the airport.
Step-by-step explanation:
Given the cab charges $0.8 per mile and $2 for tolls.
let the miles travelled by melissa be x.
The total charge is $
Now given that she can spend a maximum of $16
so the inequality is 




Therefore the maximum distance she can travel is 17.5 miles
Since the distance to airport is 25 miles which is greater than 17.5 miles she cannot afford the cab.
 
        
             
        
        
        
Answer:
- 2x² + 2x + 11
Step-by-step explanation:
Given
x² + 6 - (3x² - 2x - 5) ← distribute parenthesis by - 1
= x² + 6 - 3x² + 2x + 5 ← collect like terms
= - 2x² + 2x + 11
