Math Help - Complex numbers

1. Complex numbers

Show on diagrams:
a) All the complex numbers having real part -1
b) All the complex numbers having imaginary part 3/2

Is a) just all the numbers lying on the x axis and b) all numbers lying on the y axis?

2. Is a) just all the numbers lying on the x axis and b) all numbers lying on the y axis?
It's strange that you are ignoring numbers -1 and 3/2. What about all the complex numbers having imaginary part 3/4: is it also the y axis? So, does the exact value of the imaginary part not matter?

The real part of a complex number is its x-coordinate, and the imaginary part is its y-coordinate.

3. a) $z = -1 + yi, y \in R$
b) $z = x + i\frac{3}{2}, x \in R$
