Plot the complex number z = 2 − 4 i z=2-4i z = 2 − 4 i on the graph below.

this problem, we are asked to plot the complex number z is equal to 2 minus 4 I on the graph below. Now to solve this problem, recall that complex numbers are in the form z is equal to x plus y I, where x is the real part and y is the imaginary part. Now I can see that the real part is 2, so that means they need to go 1, 2 units to the right on the real axis. Now I can see that the imaginary part is negative 4, so that means I need to go down 1, 2, 3, 4 units on the imaginary axis. And where these lines intersect here is going to be where our complex number is. So the point 2 minus 4 I, the complex number is going to be right about there. So this is how you can plot these complex numbers on graphs like this. Hope you found this video helpful.
