Answer:
C and D
Step-by-step explanation:
in equations y=4x+9 and y=4x-9 you have the same slope (4) so paralleling is guaranteed.
y=9 and y=18 you can understand as y=0x+9 and y=0x+18, so in this situation you have the same slope (0), so lines y=9 and y=18 are parallel too.

Step-by-step explanation:

The answer is 1.16 or 0.86 because it’s 14.63/17
