Which two lines are parallel?

3x + y = -2

2y – 6x = 4

2y = -6x – 8

The answer to your question is: 2y = -6x - 8 and 3x + y = -2

Step-by-step explanation:

To know if to lines are parallel, we must find the slope of the lines, if the slopes have the same value, they are parallel.

To find the slope, just clear y from each equation and the number next to the "x" is the slope.

a) 3x + y = -2

   y = -3x - 2                          slope = -3

b) 2y - 6x = 4

   2y = 6x + 4

   y = 6/2 x + 4/2

   y = 3x + 2                          slope = 3

c) 2y = -6x - 8

   y = -6/3 x - 8/2

   y = -3x - 4                         slope = -3

Then. as the first and the last lines have the same values, they are parallel.
