Answer:
the amount of miles in 12km
Step-by-step explanation:
1. A. parallel, because when you get y by itself it is y=-2x+7, the two equations have the same slope which means they are parallel.
2. B. sometimes, in order for two lines to be parallel they have to have the same slope so, it is possible that two lines say with a slope of 3, those would be parallel BUT it doesn't always have to have a positive slope for it to be parallel like in question 1.
3. C. never, If they have the same slope they are parallel despite whatever the y-intercept is.
0.0003 would be 1/10 of 0.00003. If you divided 0.00003 by 10 you would get 0.0003.
Hopefully, this was useful.
The answer to the question is C.
