Answer:
Step-by-step explanation:
Complex numbers can be represented on an Argand diagram, where the x-axis is called the real axis and the y-axis is called the imaginary axis.
The complex number z = x + yi can be plotted on the Argand diagram as the point P(x, y), where x and y are the Cartesian coordinates corresponding to the real and imaginary parts of the complex number, respectively.
Therefore, point A is the complex number z₁ = -4 + 7i.
The product of the complex number and -1 is:
[tex]z_2=-1(-4+7i)\\\\z_2=4-7i[/tex]
This corresponds to the point in quadrant IV that is colinear with point A (see attachment).
