A rectangle is shown on the coordinate grid. On a coordinate plane, side d has points (negative 4, 3) and (0, 5), side a has points (0, 5) and (3, negative 1), side b has points (3, negative 1) and (negative 1, negative 3), and side c has points (negative 1, negative 3) and (negative 4, 3). Which equation represents the side that is parallel to side d? y = 2 x + 5 y = negative 2 x + 5 y = one-half x minus five-halves y = negative one-half x minus seven-halves
