The graph shows two distinct parallel lines in the standard Cartesian coordinate plane. Which of the following systems of linear equations could be represented by these lines?
[Graph description: A coordinate plane with two parallel lines. Line 1 passes through (0,1) and (1,3). Line 2 passes through (0,-3) and (2,1).]
2x - y = -1; 2x - y = 3
2x + y = 1; 2x - y = 3
x - 2y = -1; 2x - y = 3
2x - y = -1; 4x - 2y = -2
