Answer:
x-axis
Step-by-step explanation:
A slope of zero means a line is a horizontal line.  This would be parallel to the x-axis, since it runs horizontally.
 
        
                    
             
        
        
        
18x/18 = 2/3 • 18
Flip reciprocal of 18 which is 1/18 so it would be 2/3 • 1/18 the 2 and 18 can be simplified when cross multiples so it would then be 1/3 • 1/9 which is x=1/27
        
             
        
        
        
2 consecutive integers...x and x + 1
x + x + 1 < = 3
2x + 1 < = 3
2x < = 3 - 1
2x < = 2
x < = 1
x + 1 = 1 + 1 = 2.......the greatest possible value for the greatest integer is 2
        
             
        
        
        
I don't know if you have to do this on a graph, or just on a blank space. But, noncollinear means, "not on the same line". So, if you were to draw four points in a blank spot on a piece of paper, just draw four points in random places, making sure they aren't all directly in line with eachother. For a graph, use points like: (-6,2), (5,7), (8,3), and (1,-3). Notice that none of them have the same x or y coordinates, so they can't possibly be collinear.
        
             
        
        
        
Let 
 by the smallest of the 6 integers. Then



But 189 is odd, so it cannot be divisible by 6, which means 
 is not an integer...
