Whenever you are given the coordinates of a point, you should be able to locate it on graph paper.

Use this screen to practice that skill.

Look at the example in the figure.

It shows the point (1,1) as a black dot.

•
You are asked to locate the point

(x,y) = (1.4, -2.5) by dragging the black dot to that point.

The blue and green lines, which help identify the coordinates of the dot, will follow along.

First drag the dot *right* until the blue vertical line meets the x-axis at the number 1.4

You have moved the dot so that its x-coordinate is 1.4

•
Now drag the dot *straight down* until the green horizontal line meets the y-axis at the number -2.5

Make sure that the x-coordinate is still 1.4.

You have moved the dot so that its y-coordinate is -2.5 , and you are done.
