Which graph represents a proportional relationship? On a coordinate plane, a straight line crosses the y-axis at (0, 0). On a coordinate plane, a straight line crosses the y-axis at (0, negative 2). On a coordinate plane, a straight line crosses the y-axis at (0, negative 3). On a coordinate plane, a straight line crosses the y-axis at (0, 3).
