Answer:
(B)Use the slope formula to prove the slopes of the diagonals are opposite reciprocals.
Step-by-step explanation:
Two lines are perpendicular if the product of their slope is -1. That is, the slope of one is the opposite reciprocal of the other.
Mathematically, if their slopes are
<u>Therefore, the correct option is B.</u>
Answer:
Step-by-step explanation:
What I basically did here was take the derivative of the function to find the slope of the function at any given point. Since -2x has a slope of -2, no matter what x is, the slope will always be -2.
