To determine the correct coordinates of point B from the options provided, let's analyze the graph.

• The graph is marked in units of 10, with the x-axis and y-axis labeled. We see four points marked: A, B, C, and D. Point B is located in the top-right quadrant (first quadrant).
• The coordinates of point B should have both positive x and y values, and both should be higher than 50, since B is positioned near the top-right corner of the graph.

Let’s look at the options:

• (50, 53)
• (56.1, 48)
• (53, 53)
• (55, 50)

By visually inspecting the graph:

• Point B seems to be closer to (50, 53) or (53, 53), since it is farther along both the x and y axes.
• Comparing these options, point B is slightly higher and farther right than (50, 53), so the best estimate would be (53, 53).

Thus, the correct answer is (53, 53).
