On this screen, you will practice figuring out the (x,y)-coordinates of a given point.

Look at the example in the figure.

The point is shown as a black dot.

•
Look at the blue *vertical line* drawn through the point.

Figure out the number on the x-axis where that line meets the axis.

That number is the point's x-coordinate.

•
Look at the green * horizontal line* drawn through the point.

Figure out the number on the y-axis where that line meets the axis.

That number is the point's y-coordinate.

•
Select the 'x = ' box by clicking to the right of the equals sign.

Then type the x-coordinate of the point.

Now enter the y-coordinate in the 'y = ' box.

Click OK to check your answer.

• Click on the blue button at the top of the screen to get another point. Practice till you get the right answer quickly and easily.
