The line in the graph is horzontal and slope of a horizontal line is 0.
Determine the slope of perpendicular line as product of slope of perpendicular line is -1.
[tex]\begin{gathered} m=-\frac{1}{0} \\ =\text{undefined} \end{gathered}[/tex]The slope is undefined means line is vertical and passing through the point (2,6). So equation of line is,
[tex]x=2[/tex]Answer: x = 2
