Explanation:
Let's first put the line in slope-intercept form:
#7x-2y = 9#
#-2y = -7x + 9#
#2y = 7x - 9#
#y = 7/2x-9/2#
So the slope of the original line is
To find the slope of the perpendicular line, we take the negative reciprocal of the original slope.
#(-1)/(7/2) = -2/7#
So the perpendicular line has a slope of
