Organizing and presenting data about the distance a ball rolls down a ramp is best achieved through a line graph because this type of graph effectively illustrates the relationship between two continuous variables. In this scenario, the distance the ball rolls can be plotted against another variable, such as the angle of the ramp or time, allowing for a clear visualization of trends over this continuum.

Line graphs are particularly useful when the goal is to show how one variable changes in relation to another, making them ideal for depicting motion or progress over time. As the ramp's angle varies, the line graph can demonstrate how these changes affect the distance rolled, creating a cohesive narrative from the data.

While tables provide a structured way to present data, they do not visually convey trends as effectively. Pie charts are generally used for representing parts of a whole rather than changes in variables, making them less suitable. Bar graphs can display comparisons between distinct categories, but they do not highlight the continuous nature of the data or show how distance changes in response to varying conditions. Thus, a line graph is the most appropriate choice for visualizing the relationship in this experiment.
