For the pairs of lines defined by the following equations
indicate with an "I" if they are identical, a "P" if they are
distinct but parallel, an "N" (for "normal") if they are
perpendicular, and a "G" (for "general") if they are neither
parallel nor perpendicular.
3x+4+5=0 and y =-3x -
Y = x + 1 and 3x + 5y + 7 = 0.
У =-3x and 3x +4y +7 = 0.
