The ordered pair refers to the coordinates of the point.
We write ordered pair in the format (x,y)
Where 'x' is the value of the x-coordinate i.e. the distance of the point from the origin in the x-direction. And 'y' is the value of y-coordinate.
Now, for point T, the value of the x-coordinate is 0 as seen from the figure.
And the value of the y-coordinate is 5 as seen from the figure.
Therefore the ordered pair for the point T is (0,5)
