In such cases, we need to remember that in case of perpendicular lines, the product of their slopes is –1. This gives us a way to find the slope of the required equation -- if the slope of given line is m<sub>1</sub>, the slope of perpendicular line will be –1/ m<sub>1</sub>. The steps we need to take are as follows: <ul class="minus"> <li>Calculate slope of the new line as described above</li> <li>Extract other information provided, e.g. the y-intercept, a given point on that line etc.</li> <li>Find the equation of the new line by using the slope and the other information provided to us.<br></li> </ul> <p>This FREE mini-lesson is a part of Winpossible's online course that covers all topics within Algebra I.
