The slope of a line is the ratio of the change in the y-coordinates to the change in the x-coordinates. Looking at the line in Figure 1.9, we can see that the slope is steeper (greater) at point M than at point L. Therefore, option D is correct. The slope is zero at point J because there is no change in the y-coordinate when there is a change in the x-coordinate. The slope is the same at points J and K because the line is horizontal, so the change in the y-coordinates is zero for any change in the x-coordinates. Therefore, option C is incorrect. The slope is not greater at point K than at point L, so option A is incorrect. Similarly, the slope is not zero at all points, so option B is incorrect.
