Question #9157

what is the equation of line passing through (1,2) and perpendicular to equation y=7

Expert's answer

y=7 is a horizontal straight line. So required line is vertical (because it is perpendicular to horizontal)

general equation of vertical line is x=Const. It's given that the required line is passing through (1,2) so required equation is x=1.
