Answer with Step-by-step explanation:
For any complex number x+iy the polar form is represented as

where

Part a) x+iy = -1+i
Thus 
Thus using De-Morvier's theorem

Part 2) x+iy = 1+3i
Thus 
Thus using De-Morvier's theorem

Answer:
2/x + 3/y = 5
Step-by-step explanation:
A linear equation refers to any equation that can be written in the form;
ax+b=0 or y - mx -c = 0
The graph of a linear equation will always be a straight line; Vertical, horizontal or with a given degree of steepness (slope).
All the equations given are linear, except the last equation;
2/x + 3/y = 5. The exponents of the variables x and y is not 1 hence the equation is non-linear. Find the graph attached;
