Its slope must be the negative reciprocal of the slope of the given line.

m = -1/5

Knowing m and a given point, we can easily write the equation of the line in point-slope form.

y - y

_{1}= m(x - x_{1})y

_{1}= -13x

_{1}= 11**y + 13 = (-1/5)(x - 11)**

Set x = 0 to find the y-intercept b.

b + 13 = (-1/5)(0 - 11)

Solve for b. You can finish from here.
