Comparing Relationships with Tables: IM 7.2.7 Practice
Loading the math board and drawing, please wait…
① This example demonstrates how to compare relationships between two variables using tables, and visualizes the data points (A1, B1, A2, A3, A4, A5) in a coordinate system within GeoGebra. ② Core mathematical concepts include proportional relationships, linear relationships, converting between tables and graphs, and determining relationship types via slope or rate of change. ③ Construction highlights: based on the construction summary, multiple point objects (A1, B1, A2, A3, A4, A5) are used to mark corresponding values from the table, possibly with line segments or connections to visually compare relationships; these points can form scatter plots or line graphs to analyze proportionality. ④ Suitable for middle school (e.g., grade 7) mathematics practice, reinforcing understanding of proportional and linear relationships, and useful for classroom demonstrations or student self-exploration.

Draw a scatter plot on a coordinate plane to compare two variables. The horizontal axis represents the independent variable, and the vertical axis represents the dependent variable. Based on the given table data, plot five data points: the first point at (0.9, 2), the second at (3.1, 10), and the remaining three points positioned between them, roughly following a straight-line trend. Mark the points with solid dots, and optionally connect adjacent points with line segments to show a linear or proportional relationship. The graph should clearly display the coordinates of each point, making it easy to observe the slope or rate of change, suitable for middle school math practice on proportional and linear relationships.
