Answer:
Step-by-step explanation:
The easy way to make 2 perpendicular lines is let one be x = 3 and let y = 2.
The third line can be anything that has a minus sign in front of the x. See the graph below. The third line cannot be perpendicular to the other 2.
Sorry, the bottom of the graph got cut off. If you print out the graph and extend the vertical line and the slanted line, you will see how this works.
The three lines are
- x = 3
- y = 2
- y = -x - 2
