Algebra I

Number Properties, Operations, and Linear Equations

Students identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers, including closure properties for the four basic arithmetic operations where applicable:

♦ 
Students understand and use such operations as taking the opposite, finding the reciprocal, taking a root, and raising to a fractional power. They understand and use the rules of exponents.

♦ 
Students solve equations and inequalities involving absolute values.

♦ 
Students simplify expressions prior to solving linear equations and inequalities in one variable, such as 3(2x – 5) + 4(x – 2) = 12.

♦ 
Students use properties of numbers to demonstrate whether assertions are true or false.

Graphing and Systems of Linear Equations

♦ 
Students graph a linear equation and compute the x and yintercepts (e.g., graph 2x + 6y = 4). They are also able to sketch the region defined by linear inequality (e.g., they sketch the region defined by 2x + 6y < 4).
