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