Quizplus · Accepted Answer

The complex number -5 + 2i can be plotted on the Cartesian plane as a point with the x-coordinate of -5 and the y-coordinate of 2. Using the Pythagorean theorem, we can find the distance from the origin to this point, which is the absolute value of the complex number:
| -5 + 2i | = √((-5)^2 + 2^2) = √25 + 4 = √29.
