3. Recap Algebra I Seminar Coordinate Plane I III II IV

4. Recap Algebra I Seminar Coordinate Plane Y-axis: Vertical (up and down) X-axis: Horizontal (left and right) Number lines (positive and negative) Positive: Up and Right Negative: Down and Left

5. Recap Algebra I Seminar Coordinate Points or Ordered Pairs

6. Recap Algebra I Seminar Plotting Coordinate Points

7. Recap Algebra I Seminar Slope Symbol: m Equation:

8. Recap Algebra I Seminar Slope Equation: Find the slope between these two points: (2,3) and (4,5)

9. Slope on the Coordinate Plane (2,3) and (4,5)

10. Recap Algebra I Seminar Slope Intercept Form Equation of a Line in Slope Intercept Form: y = mx+b M = slope b = y-intercept (where the line crosses the y-axis)

11. Algebra I Seminar Graphing a Line in Slope Intercept Form y = mx + b y = 2x + 1 b = 1: y-intercept m = 2: slope

12. Recap Algebra I Seminar Now You Do It! Get out a piece of paper Put the following equations in Slope Intercept Form Graph 1 of the equations Y=3x-4 2+y-x=0 2y=2x+4 X=2y
