Let x be the amount of weeks.
60 + 7x = 120
60 - 60 + 7x = 120 - 60
7/7x = 60/7
x = 8.571428571
        
             
        
        
        
Answer:
C. They are the same line. 
Step-by-step explanation:
In order to compare the linear equations given, they need to be in the same form.  The best form in order to evaluate slope and y-intercept is slope-intercept form, y = mx + b.  Since the second equation is already in slope-intercept form, we need to use inverse operations to convert the first equation: 
6x - 2y = 16 ----  6x - 2y - 6x = 16 - 6x ----  -2y = -6x + 16 
-2y/-2 = -6x/-2 + 16/-2
y = 3x - 8
Since both equations are in the form y = 3x - 8, then they are both the same line.
