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>

There would be no solution because when you multiply the bottom equation by 2 it would equal to -8x +2y = 6. So when you add that equation to 8x - 2y = 1, 0x or 0y would not equal to 7.
Hope this helps :)
