Answer: Midline equation: y = -7

Explanation: This function is a sinusoidal function of the form:

y = a.cos(b(x+c))+d

Midline is a horizontal line where the function oscillates above and below.

In the sinusoidal function d represents its vertical shift. Midline is not influenced by any other value except vertical shift. For that reason,

Midline, for the function:
h(x) = -4cos(5x-9) - 7 is y=d, i.e.,
y=-7
