Given a slope m of a line, the slope of a perpendicular line will be the negative reciprocal of m, this means the following:


m_p=-(1)/(m)

notice that the first equation is written in slope intercept form, then the slope is m = 3.

The negative reciprocal of m is -1/3, since the second equation has slope -1/3, we have that both lines are perpendicular, thus, the answer is True
