Which lines have the same slope (parallel lines are inconsistent)
The first have the same slope but same intercept, so same line
The second has slope -3/2 and 3/2, so not parallel
The third has slope -2 and different intercept. so C. ANSWER
The fourth if the first is multiplied by 2 gives the second, so that is the same line.
