Start by determining the slope of the line represented by your given equation. To do that, put the given equation into slope-intercept form. To do that, solve the equation for in terms of everything else. For your problem, add to both sides of the equation and then multiply both sides of the equation by . The slope of the line represented by the given equation will then be the resulting coefficient on .

The slopes of perpendicular lines are negative reciprocals. That is to say:

So, once you have determined the slope of the line represented by the given equation, determine the negative reciprocal of that slope. If the slope is a fraction, turn the fraction over and change the sign.

The equation is in the "standard form"
You need to get it in the "slope-intercept" form
which is:

In this form, is the slope

Subtract from both sides

Divide both sides by

Now it is in the slope-intercept form
where
The rule is, that any line perpendicular to this line will have
slope =

The slope of any line perpendicular to
is
