Competency 3—Knowledge of algebraic thinking and the coordinate plane
Determine whether two algebraic expressions are equivalent by applying properties of operations or equality.
Identify an algebraic expression, equation, or inequality that models a real-world situation.
Solve equations and inequalities (e.g., linear, quadratic) graphically or algebraically.
Determine and solve equations or inequalities, graphically or algebraically, in real-world problems.
Graph and interpret a linear equation in real-world problems (e.g., use data to plot points, explain slope and y-intercept, determine additional solutions).
Identify relations that satisfy the definition of a function.
Compare the slopes of two linear functions represented algebraically and graphically.
