Grade: 8

Subject: MATH

Domain: The Number System

Theme: Know that there are numbers that are not rational, and approximate them by rational numbers

Grade: 8

Subject: MATH

Domain: The Number System

Theme: Know that there are numbers that are not rational, and approximate them by rational numbers

Theme: Analyze and solve linear equations and pairs of simultaneous linear equations

Standard Description: Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.

Domain: Expressions & Equations

Theme: Analyze and solve linear equations and pairs of simultaneous linear equations

Standard Description: Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

Domain: Expressions & Equations

Theme: Analyze and solve linear equations and pairs of simultaneous linear equations

Standard Description: Solve real-world and mathematical problems leading to two linear equations in two variables. For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.
