# Write all of the complex numbers that are graphed in the complex plane shown. A: _ + _i, B: _ + _i, C: _ + _i, D: _ + _i

A complex number is the sum of a real number and an imaginary number and it is represented as x + iy and is usually represented by z.

## Answer: The complex numbers that are graphed in the complex plane shown are, A: -2 + 3i, B: -1 - 1i, C: 3 - 4i, D: 4 + 1i

Let's look into the solution below.

**Explanation:**

A complex number is represented as z = x + iy. Here, both x and y are real numbers.

- x is called the real part which is denoted by Re(z).
- y is called the imaginary part which is denoted by Im(z).
- iy is an imaginary number.

Based on the definition we will look into the x and y coordinates of each of the points A, B, C, and D showed in the graph.

Let's look into the coordinates (x,y) of each of these points along with their representation in complex form.

Coordinates of the Points (x,y) | Complex Number Representation = x + iy |

A(-2, 3) | -2 + 3i |

B(-1, -1) | -1 - 1i |

C(3, -4) | 3 - 4i |

D(4, 1) | 4 + 1i |
