Take note that the slope is , which can be written as . Flip this fraction and change the sign to get . Now it turns out that any equation of the form (where "b" is a constant) is perpendicular to .

So the equations , , , , etc.. are all perpendicular to

perpendicular lines have slopes that are negative reciprocals

y = -(1/2)x + b, where b is any real number
