1. The problem gives a table showing jump heights (meters) depending on ankle weights (kilograms). 2. The independent variable is the one that you control or choose values for. Here, David chooses the ankle weights. 3. The dependent variable depends on the independent variable. Here, the jump height depends on the ankle weight. 4. In graphs, the independent variable is placed on the x-axis (horizontal axis). 5. The dependent variable is placed on the y-axis (vertical axis). 6. Therefore: - The independent variable is the ankle weight and should be placed on the x-axis. - The dependent variable is the jump height and should be placed on the y-axis. Final answers: - Independent variable: ankle weight, placed on x-axis. - Dependent variable: jump height, placed on y-axis.
