Answer:
Hi, your answer is y= -3
-3
Step-by-step explanation:
We will use the slope-intercept formula which is 

We will use two points in this case I'll use 
(-2,-2) and (-8,1)
 =
= which can be simplified as
 which can be simplified as 
Your Y will be -3
which your final answer will be y=-1/2x-3
Hope this helps :)

45/60=0.75. Speed*time=distance. 35(0.75)= 26.25 miles
        
                    
             
        
        
        
Answer:
n = 61 costumers
Step-by-step explanation:
For calculating the number of costumers he should sample we use the next equation:

                           Where E is the error that we are prepared to accept, in this  case E = 0.15
 
How we don't know the value of p, we can estimate it like p = 0.5
∝ = 1-0.98 = 0.02
1-∝/2 = 0.99


n = 60.32 costumers
n ≈ 61 costumers
