Final answer:
To determine changes in a system on graphs, examine the two-dimensional data plot with the relationship between independent and dependent variables charted on a line graph. The slope of the line reflects changes in the system, and care must be taken to avoid misinterpretations due to misleading graph features.
Step-by-step explanation:
To determine what has been changed in a system on graphs, we focus on the relationship between two properties of a system, which can be represented on a two-dimensional data plot. This plot consists of two axes: the horizontal axis (x-axis) for the independent variable and the vertical axis (y-axis) for the dependent variable. The independent variable represents the controlled aspect, such as time, while the dependent variable corresponds to the observed change, such as distance.
A line graph is particularly useful for showing how one variable responds to changes in another over time. For instance, if we plot time versus distance for a train leaving a station, these two variables are plotted with time on the x-axis and distance on the y-axis. The slope of the line on the graph indicates the speed at which the train is traveling. By analyzing the graph, we can observe changes such as accelerations, decelerations, or constant speeds. It's important to note that while graphs can clarify trends and patterns, they can also be misleading. When assessing changes on a graph, one must consider scale, labeling, and context to ensure the graph's integrity is not compromised.
