You can put this solution on YOUR website! Is x=2,y=9 a parallel line, perpendicular line, or neither of these two lines. thanks for your help.
x=2 is a vertical line going through the x-axis at 2 with an undefined slope.
y=9 is a horizontal line going through the y-axis at 9 with a slope of 0.
horizontal and vertical lines hit each other at a 90 degree angle and are therefore perpendicular.
Happy Calculating!!!
