I think there is a bug here. They can't be whole numbers.
Answer:
c is parallel to d
Step-by-step explanation:
the degrees need to be equal in order for them to not intersect at any point, if you set x = 10 as given.
I will say there are two ways to solve this problem. The first is, you can use your calculator and calculate it to see which is the closest to 2. The second way is divide it and here is how you do it:
1 is just 1
15/16 = 16 goes into 15 for less than one
17/8 = 8 goes into 17 for more than two so you can rewrite it as

63/33 = 33 does not go into 63 for two
So the answer is 17/8
This would simply be y=8x. Which is not one of the options. Are you sure that is the function?
I’m not sure if you need the steps but x is -4 and y is -1
