Answer: it's C Sophie used the wrong height for the pyramid
It's Right cause I took the test.
Step-by-step explanation:
d1 = ax + by + c = 0 and d2= mx + ky + f = 0
if they are parallel :

8x + 2y = 7
8x + 2y - 7 = 0
- 8x + 2y -9 = 0
- 4x + y -6 = 0
- 16x + 4y - 19 = 0
you can create more whatever you want =)
