Which mode allows users to draw perpendicular lines?

90° straight lines can be drawn by switching the Ortho Mode to ON. or by pressing Function key (F8). Ortho mode is used.

What is the equation of a line perpendicular to another?

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.
