Question 328388: Good morning,
Here is my question
What is the relationship of the lines which have equations of y=2 and x=0
A. Parallel
B. Perpendicular
C. Intersecting
D. Not enough info to tell
I know y=2 will create a horizontal on the y-axis at point 2. And I know 0 can't be plotted. Yet the question is so tricky I'm sure it can't just be D.
Any help is welcome
