Just simplify the given equation
y = 7.2 + 4(x-2)
y = 7.2 + 4x - 8
y = 4x - 0.8
Now they want to know the answer if X = 2
y = 4(2) - 0.8
y = 8 - 0.8
y = 7.2
        
             
        
        
        
Im doing this too also, 
X is greater than equal to negative 4 on the graph closed circle going right>>>>
X is less than equal to 3 closed circle going left....
