Graph: A diagram that exhibits a relationship, often functional, between two sets of numbers as a set of points having coordinates determined by the relationship; also called plot.

Resources for this term:
Interpreting Distance-Time Graphs
Interpreting Distance-Time Graphs

Students connect descriptions of everyday situations with distance-time tables and graphs and relate speeds to the slopes of the graphs.

Forming Quadratics
Forming Quadratics

Students use algebra and graphs to explore how the standard, factored, and completed square forms of a quadratic relate to the intercept, roots, maxima, and minima of function.

Sorting Equations and Identities
Sorting Equations and Identities

Students sort algebraic statements into identities, equations with solutions, and equations with no solutions, using manipulation and substitution to justify their choices.

Defining Regions Using Inequalities
Defining Regions Using Inequalities

Students combine linear inequalities, correctly representing them on a graph, to identify a set of solutions.

Modeling Situations With Linear Equations
Modeling Situations With Linear Equations

Students explore relationships between variables in everyday situations using graphs, tables, and formulae.

Optimization Problems: Boomerangs
Optimization Problems: Boomerangs

Students solve a problem of optimizing within constraints and then explore alternative algebraic and graphical approaches involving systems of linear equations.
