Question

Which complex number is represented by the point graphed on the complex plane below?

Answer 1

Answer is C on 3dgenuity

Answer 2

Answer: The answer is (c) 3 - 4i.

Step-by-step explanation:  We are given a point located on the complex plane and we are to select the correct complex number that is represented by this point.

We can see that the co-ordinates of the point on the plane are (3, -4).

Since the point (a, b) can be written in the form a + bi, where 'a' is the measurement along X-axis and 'b' is the measurement along Y-axis, so the point (3, -4) an be written in the following form:

(3, -4) = 3 + (-4)i = 3-4i.

Thus, (c) is the correct option.
