Functions and graphs: Data and graphs
A scatter plot
Below you can use the
- point button to draw or move a point and
- eraser button to delete a point.
Note: if you click for a point on the origin of the coordinate system, you do not select a new point in the graph. You can also see this because no blue point is created, but a smaller black point indicating the origin. If you draw a point on an axis, then you can only move it along this axis.
Now draw the point graph for the following measurements \[\begin{array}{|r|r|} \hline x & y\\ \hline -3 & 1\\ \hline\hline 0 & 2\\ \hline 3 & 2\\ \hline\end{array}\]
