Answer:

The ordered pair that corresponds to point P is: (4, 2)

Step-by-step explanation:

It is clear from the graph that the point P is located at the location (4, 2).

In other words,

at x = 4, y = 2

It means:

The x-coordinate of the point P is: x = 4

The y-coordinate of the point P is: y = 2

Thus, the location of the point P →  P(x, y) = P(4, 2)

Please check the attached graph.

Therefore, we conclude that:

The ordered pair that corresponds to point P is: (4, 2)
