We know the midpoint formula is \((\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})\) . Plugging our values in, we get \((\frac{4+x_2}{2}, \frac{5+y_2}{2})=(1,-2)\) . Solving for \(x_2,\) we attain \(\frac{4+x_2}{2}=1, 4+x_2=2, x_2=-2\) and \( \frac{5+y_2}{2}=-2, 5+y_2=-4, y_2=-9\) . Thus, the order pair is \(\boxed{(-2,-9)}\) .
