A line of slope 6/5
When two lines are parallel, their slopes are equal
When two lines are perpendicular, the sum of their slopes is -1

Answer:

Explanation:

If two lines given with slope
m_(1) and
m_(2) then the lines will be perpendicular to each other if


m_(1) ×
m_(2) = -1

Now we come to question, one line has been given with


m_(1) =
((-5)/(6))

so slope of another line will be


((-5)/(6)) ×
m_(1) = -1


m_(1) =
((-1))/(((-5)/(6) ))

=
((6)/(5))

so perpendicular line to the line having slope =
((-5)/(6)) will be with the slope of
((6)/(5)) irrespective of y-intercept made by the lines.
