Foundations in Algebra: Reasoning with Equations and Inequalities

FA.AREI.1

Fully covered
Understand and justify that the steps taken when solving simple equations in one variable create new equations that have the same solution as the original.
(Content unavailable)

FA.AREI.3

Fully covered
Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.

FA.AREI.5

Fully covered
Justify that the solution to a system of linear equations is not changed when one of the equations is replaced by a linear combination of the other equation.

FA.AREI.6

Solve systems of linear equations algebraically and graphically focusing on pairs of linear equations in two variables. (Note: FA.AREI.6a and 6b are not Graduation Standards.)

FA.AREI.6a

Fully covered
Solve systems of linear equations using the substitution method.

FA.AREI.6b

Fully covered
Solve systems of linear equations using linear combination.

FA.AREI.10

Fully covered
Explain that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane.

FA.AREI.11

Fully covered
Solve an equation of the form f(x)=g(x) graphically by identifying the x-coordinate(s) of the point(s) of intersection of the graphs of y=f(x) and y=g(x). (Limit to linear; quadratic; exponential.)

FA.AREI.12

Fully covered
Graph the solutions to a linear inequality in two variables.
