&lt;b&gt;Step 1:&lt;/b&gt;  Put the given equation into slope-intercept form by solving the equation for *[tex \Large y] in terms of *[tex \Large x].


&lt;b&gt;Step 2:&lt;/b&gt;  Determine the slope of the given equation by inspection of the coefficient on *[tex \Large x] in the slope-intercept form derived in Step 1.


&lt;b&gt;Step 3:&lt;/b&gt;  Use


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  L_1 \perp L_2 \ \ \Leftrightarrow\ \ m_1 = -\frac{1}{m_2} \text{ and } m_1, m_2 \neq 0]


to find the slope of the perpendicular.  Which is to say, compute the negative reciprocal of the value discovered in Step 2.
