Question

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. Be careful! You have only TWO attempts!


1) 3x+4y+5=0 and y=−3/4x−5/4.

2) x=√2 and y=π.

3) y=x+1 and 3x+5y+7=0.

4) y=−3/4x and 3x+4y+7=0.
