Expressions and Equations
Represent and analyze quantitative relationships between dependent and independent variables.
9. Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation d = 65t to represent the relationship between distance and time.

GeoGebra is Java based software which can be downloaded or run through a browser to dynamically model geometry and algebra concepts. The robust interface allows the user to construct either algebraic or geometric mathematical objects on a Cartesian coordinate plane and manipulate those objects through both of their algebraic and geometric forms. Users can design GeoGebra sketches for other users to address specific concepts. Inputs include: points, lines, perpendicular or parallel lines, circles, polygons, conic sections, angles, and transformations of existing objects.
