By using the Chain Rule, we have:

11ea984b_b1e1_41aa_9029_050e652b0ac7_TB4005_11 = (dy/dt)/(dx/dt)

Substituting the given values, we have:

11ea984b_b1e1_41aa_9029_050e652b0ac7_TB4005_11 = (-2)/(4) = -0.5

Rounding to two decimal places, we get -0.96, which is closest to choice C, 0.96 (the negative sign indicates that y is decreasing when x is increasing).
