Final answer:
The coordinates of Ry-axis (H) are (0, y), Rx=3 (G) has the coordinates (3, 0), and Ry=4 (FGH) is represented by the point (0, 4) on the graph.
Step-by-step explanation:
To determine the coordinates of Ry-axis (H) and Rx=3 (G), we need to understand the Cartesian coordinate system. The Ry-axis refers to the y-axis, which represents the vertical line on the graph. Therefore, the coordinates of H will be (0, y), where y can take any value on the vertical axis. The coordinates of Rx=3 (G) will be (3, 0), indicating the point on the x-axis at x=3. To graph and label Ry=4 (FGH), we plot the point (0, 4) on the graph and label it as FGH.
