Equations of Perpendicular Lines
... line y = −3x + 4. Step 1 Find the slope of the perpendicular line. The graph of the given equation has a slope of −3. Because the slopes of perpendicular lines are negative reciprocals, the slope of the perpendicular line passing through (−3, 8) is —13. Step 2 Use the slope m = —13 and the slope-int ...
