In general, two lines that are perpendicular have slopes that are negative reciprocals of each other.
The only exception are horizontal lines and vertical lines. This is important in this case.
y = 3 is a horizontal line. The line perpendicular to this line is a vertical line. Vertical lines always have the equation x = h. In this case, h must equal 4, so that the line passes through the point (4, -6).
So in the first case, the line perpendicular to y = -3 that passes through point (4, -6) is the line x = 4.
x = 20 is a vertical line. The line perpendicular to this line is a horizontal line. Horizontal lines always have the equation y = k. In this case, k must equal -5, so that the line passes through the point (0, -5).
So in the second case, the line perpendicular to x = 20 that passes through point (0, -5) is the line y = -5.
