The equation y = -1 represents a horizontal line passing through the point (0, -1). Since the slope of a horizontal line is always 0, the slope of this line is 0. The y-intercept is the point where the line crosses the y-axis, which in this case is (0, -1). Therefore, the slope is 0 and the y-intercept is -1, so the answer is D) m = 0, b = -1.
