Final answer:
Perpendicular lines have slopes that are negative reciprocals of each other.
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of each other. In other words, if the slope of one line is m, the slope of the perpendicular line is -1/m.
For example, if the slope of Line A is 3/4, then the slope of the perpendicular Line B is -4/3. Similarly, if the slope of Line A is -2, then the slope of the perpendicular Line B is 1/2.
Therefore, the statement 'Perpendicular lines have slopes that are flipped and have the opposite sign' is false.
