y-intercept is the Y value when x is 0
 Y = 60
 so this means if a person studies 0 hours they will get a 60 on the test
 So B would be the answe
 
        
                    
             
        
        
        
That is not a question so I can't help you but combined she did 7/4 or 1 3/4 hours
        
             
        
        
        
(-3,0) and (5, -2)
slope = (0 + 2)  /(-3 - 5) = -2/8 
y - 0 = -2/8 (x + 3)
y = -2/8 x - 6/8
8y = -2x - 6
2x + 8y = - 6
Answer is 
D. 2x + 8y = -6
