The point is located in the complex coordinate system where the horizontal axis represents the real part (Re) and the vertical axis represents the imaginary part (Im). Given that the horizontal coordinate is 1 and the vertical coordinate is -4, the representations of this point are as follows:

1.(1, -4): This is a Cartesian coordinate representation, indicating the location but not typically used for complex numbers.

2.1 - 4i: This is the correct representation of the point in the complex plane, indicating a real part of 1 and an imaginary part of -4. <...
