The equations x minus 2 y = 1, 3 x minus y = negative 1, x + 2 y = negative 1, and 3 x + y = 1 are shown on the graph below.

On a coordinate plane, there are 4 lines. Green line goes through (0, negative 1) and (1, negative 1). Orange line goes through (negative 1, negative 1) and (0, 1). Pink line goes through (0, 1), and (2.5, negative 1). Blue line goes through (0, 1) and (negative 2.5, negative 1).

Which system of equations has a solution of approximately (0.6, –0.8)?
x + 2 y = negative 1 and 3 x + y = 1
x minus 2 y = 1 and 3 x + y = 1
x minus 2 y = 1 and 3 x minus y = negative 1
x + 2 y = negative 1 and 3 x minus y = negative 1
