Writing Equations of Perpendicular Lines

Writing Equations of Perpendicular Lines 1.6 - Solution

arrow_back Return to Writing Equations of Perpendicular Lines

Two lines are perpendicular if and only if the product of their slopes are equal to Consider the first equation. Here, the slope is This means that the slope of any perpendicular line will satisfy the equation To find this slope we'll multiply both sides by We can see that in Ron-Jon's equation he wrote the slope which is incorrect. The correct equation should be
