Answer:
C. -2x + y = 2
Step-by-step explanation:
Two lines which are parallel to each other should have the same slope,
looking at A: slope m = -2 not equal to 2
looking at B: slope m = -2
looking at C: slope m = 2
looking at D: slope m = -2
your answer is 4.5 you're welcome :-)
When you divide the top and bottom you get a decimal number. So you compare those. Or if you draw it out then you can see that 21/30 is bigger.
