1. Which point(s) lie on the x-axis?

   If you look at the graph, the points V and R lie on the x-axis. This means that the y-coordinate for both points must be zero.

2. What is the y-coordinate of point S?

   To find the y-coordinate for point S, draw a line from point S to the y-axis. From this we can see the y-coordinate is 25.

3. What are the coordinates of point Q?

   If you look at the figure above, point Q lies on the y-axis. This means that the x-coordinate must be zero. If you count how far the point lies along the y-axis from the origin, you will find the y-coordinate is 10. Therefore, the (x, y) coordinates for point Q is (0, 10).

4. What are the coordinates of point T?

   To find the coordinates for point T: The line drawn from point T down to the x-axis intersects the x-axis at 15. The line drawn from point T to the y-axis intersects the y-axis at 20. Therefore, the (x, y) coordinates for point T is (15, 20).
