two perpendicular lines intersect in the y-axis. the equation of one line is y-6x-6=0. determine the equation of the other line

y-6x - 6=0

y = 6x + 6; slope = 6 and y intercept b = 6

Perpendicular lines, slope is opposite and reciprocal

so other line has slope = - 1/6, they both intersect in y a-xis so they intersect at (0,6) so other line also has b = 6

Equation of other line

y = - 1/6 x + 6
