Graphing linear inequalities

  1. 1. Graphing Linear Inequalities
  2. 2. Vocabulary Terms ● Boundary Lines ● Linear Inequality
  3. 3. Steps to Graphing 1. Linear Equations vs. Linear Inequalities ● Drop the inequality sign. y<2x+3 ● Change to a linear equation. y=2x+3
  4. 4. Steps to Graphing 2. Solve for y. -2x+y= 3 +2x +2x y=2x+3
  5. 5. Steps to Graphing 3. Graph the equation. y=2x+3
  6. 6. Steps to Graphing 4. Determine the boundary lines. < > equals dotted line < > equals solid line
  7. 7. Steps to Graphing 5. Replace the equation with the original statement of inequality. Change y=2x+3 back to y<2x+3.
  8. 8. Steps to Graphing 6. Shade y< or y< shade below y> or y> shade above
  9. 9. Linear Inequalities Graphing Systems
