Compacted Mathematics Grade 8 (with Integrated Math I): Algebra: Reasoning with Equations and Inequalities (A-REI)

Solve equations and inequalities in one variable

A-REI.3

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

Solve systems of equations

A-REI.5

Fully covered
Given a system of two equations in two variables, show and explain why the sum of equivalent forms of the equations produces the same solution as the original system.

A-REI.6

Fully covered
Solve systems of linear equations algebraically, exactly, and graphically while focusing on pairs of linear equations in two variables.

Represent and solve equations and inequalities graphically

A-REI.10

Fully covered
Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).

A-REI.11

Fully covered
Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, quadratic, absolute value, and exponential functions.

A-REI.12

Fully covered
Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.
