Answer:
-1/12
Step-by-step explanation:
The slopes of perpendicular lines are equivalent to -1.

Step-by-step explanation:
- 5x+12=6x+7 (opposite sides of a parallelogram are equal)
- 12=x+7 (subtract 5x from both sides)
- x=5 (subtract 7 from both sides)
- Now put x in any of the equations-- 5(5)+12=37 or 6(5) +7=37
That is not the specified answer
