The midline of the graph is y = -3.9.

The midline of a trigonometric function is the horizontal line about which the function oscillates.

In the given graph, the minimum point is at (2,-0.9) and the amplitude is 3.

Since the minimum point is below the midline, we can determine the midline by subtracting the amplitude from the minimum y-value.

Therefore, the midline is given by the equation:

y = -0.9 - 3 = -3.9
