Answer:
1
Step-by-step explanation:
identify two points on the graph:
1. (0, 4)
2. (-2, 2)
use slope formula: (y² - y¹) / (x² - x¹)
1. (2 - 4) / (-2 - 0) = -2 / -2 = 1
slope = 1
 
        
                    
             
        
        
        
If n = number of hours and the equation is 174 + 58n then the answer is 3 hours
174 = 58n
    
     ÷  58
3  =  n
