Rewriting the equation of the given line in slope-intercept form,


2x-3y=13\\\\2x-13=3y\\\\y=(2)/(3)x-(13)/(3)

Thus, the slope of the given line is 2/3. Since perpendicular lines have slopes that are negative reciprocals of each other, we want to find the line with a slope of -3/2.

Substituting into point-slope form,


y-5=-(3)/(2)(x+6)\\\\y-5=-(3)/(2)x-9\\\\\boxed{y=-(3)/(2)x-4}
