"Undefined" slope means the line on the graph is vertical, and that 
tells the whole story right there.  The 'x' coordinate is the same for 
every point on the line.  If  (6, -1)  is a point on the line, then you know 
that the x-value of EVERY point on it is  6 .  
It's a vertical line that intersects the x-axis at  x=6,  and the equation 
of the line is  x=6 .
