Plotting Grid Coordinates
What are the sailboat's grid coordinates?
OBJECTIVE: To practice plotting Cartesian point coordinates on a GeoGebra sheet
In a previous lesson, you learned how to plot point coordinates on the Cartesian plane. This lesson will provide you some practice at plotting Cartesian coordinates on a GeoGebra sheet using the
Point tool and connecting the dots using the 
Line Segment tool.
Point tool and connecting the dots using the Line Segment tool.How to Plot Points and Draw Line Segments
Plot these points on the GeoGebra sheet below using thePoint tool and connect the dots using the Line Segment tool.
Use the 
Move Graphics View tool, the 
Zoom In tool and the
Zoom Out tool to adjust your working area. You will need at least 27 units above and 15 units below the x-axis, and at least 20 units on either side of the y-axis.

TODAY you practiced plotting Cartesian coordinates on a GeoGebra sheet using the Point tool and learned to connect points using the Line Segment tool.
In the future, you'll learn how to do more complicated Geometric constructions. Let's look forward to that!
