Answer:
AB represents a line segment because the points limit the line from continuing on either end.
If you include the ray on the left side, then it would be considered a ray. 
 
        
                    
             
        
        
        
One possible system is 
1x + 3y = 4
2x + 6y = 8
Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.
In other words, the second equation is the result of multiplying both sides of the first equation by 2.
1x+3y = 4
2*(1x+3y) = 2*4
2x+6y = 8
Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.

Answer:
   -361
Step-by-step explanation:
Your calculator can tell you the result. It is -361.
Start with the inner parentheses and work outward. Do multiplication and division in the order shown, left to right, before addition or subtraction.
   -3[2/6+8{-9/3(8-5*3)-6}]
   = -3[2/6+8{-9/3(8-15)-6}]
   = -3[2/6+8{-9/3(-7)-6}]
   = -3[2/6+8{-3(-7)-6}]
   = -3[2/6+8{21-6}]
   = -3[2/6+8{15}]
   = -3[1/3+8{15}]
   = -3[1/3+120]
   = -3[361/3]
   = -361
 
        
             
        
        
        
I believe it would be the last answer, 6.25
if this is correct i’m very sorry, but if this helps, please mark brainliest. :)
