Which system of equations is represented in the graph?

On a coordinate plane, a horizontal line is at y = negative 2 and another line goes through (0, negative 3) and (6, 0).
y = negative 2. x minus 2 y = 6.
y = negative 2. x + 2 y = 3.
x = negative 2. 2 x minus y = 3.
x = negative 2. 2 x + y = negative 3.
