Take note that the slope is m=2, which can be written as m=2%2F1. Flip this fraction and change the sign to get m=-1%2F2. Now it turns out that any equation of the form y=-%281%2F2%29x%2Bb (where "b" is a constant) is perpendicular to y=2x%2B3.

So the equations y=-%281%2F2%29x%2B2, y=-%281%2F2%29x%2B1%2F3, y=-%281%2F2%29x%2B55, y=-%281%2F2%29x%2B11, etc.. are all perpendicular to +y=+2x+%2B3

perpendicular lines have slopes that are negative reciprocals

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