Interesting linear equations problem involving slopes of perpendicular lines.?
Determine the value of "n" if the lines nx - 2y + 8 = 0 and 3x + ny + 6 = 0 are PERPENDICULAR.
Now I know that the slopes of perpendicular lines are negative reciprocals of each other, but I just don't see how to set the system up to solve for "n".
