1. The problem statement, all variables and given/known data Draw the set of points in the complex plane satisfying the equation |z + 3i| = 4 2. Relevant equations 3. The attempt at a solutionI don't know what z is supposed to be. In class, we've been using z to stand for a complex number (x + yi). Am I supposed to substitute that into the equation? Or, am I supposed to treat z like any real number and find the absolute value?
