Write m = 21 - 72i as an ordered pair in an Argand diagram.

m = 21 - 72·i in an ordered pair =  (21, -72)

Step-by-step explanation:

Graphing complex numbers involves the application of the methodology of graphing real numbers on the coordinate plane in addition to the Argand coordinate plane to form the complex coordinate plane, such that where the complex number is of the form a + bi, the real part of the complex number, a, is taken as the x-coordinate value while the imaginary part, b, is taken as the y-coordinate value

As such to represent the complex number as an ordered pair, we have;

a + bi is equivalent to (a, b)

Therefore;

To write the complex number, m = 21 - 72·i as an ordered  pair in an Argand diagram, we have;

m = 21 - 72·i in an ordered pair =  (21, -72).
