Step-by-step explanation:
16 (2x + y - 3)
 
        
             
        
        
        
The -1 means that y = -1, so point is one unit below the x-axis.  In (5, -1), the x is positive, which could put the point in either the first quadrant or the fourth.  With the y being negative, however, it means that the point is in the fourth quadrant.  Those are your 2 true statements.
