Browse by Grade & Topic: Graphing in the Coordinate Plane

Explore the slope of a line, and learn how to calculate slope. Adjust the line by moving points that are on the line, and see how its slope changes.

Identify the coordinates of a point in the coordinate plane. Drag the point in the plane and investigate how the coordinates change in response.

Compare the standard form of a linear equation to its graph. Vary the coefficients and explore how the graph changes in response.

Compare the point-slope form of a linear equation to its graph. Vary the coefficients and explore how the graph changes in response.

Compare the slope-intercept form of a linear equation to its graph. Vary the coefficients and explore how the graph changes in response.

Compare the graph of a linear function to its rule and to a table of its values. Change the function by dragging two points on the line. Examine how the rule and table change.
