Alg1 7.13 Graphing Linear Inequalities Presentation Transcript

  • 1. Algebra 1 Lesson 7.13 Graphing Linear Inequalities
  • 2. Table Discussion Graphing Inequalities Graphing "equalities"
  • 3. Review: Graphing Linear "Equalities" HOY Horizontal Slope: "0" y= ____ & VUX Vertical slope: undefined x = _______
  • 4. Review: Graphing Linear "Equalities" slope y-intercept y = mx + b 1x + 2 y=4
  • 5. What does the... line mean? 1x + 2 y=4 all the points on the line are solutions
  • 6. What are the 4 inequalities? *Boundary line Less than Greater than Less than or equal to Greater than or equal to
  • 7. Graphing Linear Inequalities y>5 x < -6
  • 8. Graphing Linear Inequalities y ≥ -2 y<4 x≤3 x > -5
  • 9. Review: Graphing Linear "Equalities" = 1x+2 y>4
  • 10. Review: Graphing Linear "Equalities" = 3x - 2y ≤ -2
  • 11. 2x + 5y = 10 2x + 5y = 10
  • 12. 3x + y = -6 3x + y = -6
