Answer:
C. Each has a slope of –3, but one has a y-intercept of 3 and the other has a y-intercept of –1, which makes the lines parallel.
Step-by-step explanation:
Parallel lines will have no solution, since they share no points. To be parallel, they will have the same slope and different intercepts.
___
If the intercepts and slopes are the same, the lines are identical and there will be an infinite number of solutions.

Answer:
A
Step-by-step explanation:
Formula for circumference is 2πr=C
80/2 gives you the radius which is 40.
40×2=80
pi=3.14
80×3.14=251.2 which is 251 or A
