  2. Rational Numbers • Addition and Subtraction • GET A COMMON DENOMINATOR and add or subtract the numerators • Examples: 1. • 2.

  3. Multiplication and Division • Multiplication: Multiply the numerators together and the denominators together. • Division: Multiply the first fraction by the reciprocal of the second fraction. • Examples: 1. • 2. • HOMEWORK: p.432 #1

  4. ALGEBRA REVIEW • Evaluating expressions: Rule: Substitute in the values of the variables and use BEDMAS Ex. 1 Evaluate y if x = -2: Ex. 2 Evaluate y if x = 3: HOMEWORK: p. 433 # 1

  5. ALGEBRA • Rules: • Only LIKE TERMS may be added or subtracted • When multiplying or dividing, use exponent laws • Distributive Property: • a(b+c) = axb + axc • Foil: • (a+b)(c+d) = ac + ad + bc + bd

  6. Examples: Simplify • 1. • 2.

  7. 3. Evaluate if m = -4 and n = 2: • HOMEWORK: p.423 # 1, p.430 # 1, p. 422 # 1

  10. Graphing a quadratic relation using a table of values Example 2: Graph

  11. Graphing a quadratic relation using a table of values • Example 1: Graph • HOMEWORK: p. 426 #1

  12. Key Features of Quadratic Relations • 1) Direction of opening • 2) The vertex • 3) The equation of the axis of symmetry • 4) The x-intercepts • 5) The y-intercept • HOMEWORK : p.429 # 1
