| Geogebra Plot the points A(4, -3) and B (-2, 5). Join them and find the equation of the line passing through these points. |
1. Open Geogebra. Make sure that the Co-ordinate Axes and the Grid is displayed. 2. Click on Tool No 2, and Select ‘New Point Tool’. |  Figure 1 |
3. Click on the point (4, -3). A new point A will be plotted as shown. |  Figure 2 |
4. Click on the point (-2, 5). A new point B will be plotted as shown. |  Figure 3 |
5. Click on Tool No 3 and select ‘Line between 2 points Tool’. |  Figure 4 |
6. Click on point A followed by point B. A line will be drawn through points A and B and the equation of this line will be displayed in the Algebra section of the display. 7. Save your file or print it if required. |  Figure 5 |

ReplyDeleteStep 5 is wrong. It should be Click on Tool No 3 and select ‘Line through 2 points Tool’.
ReplyDeleteStep 7: Coordinate values do not match that with assignment (igure 5). Line equation thus is wrong)
