Lets do this step by step.
This is the trigonometric form of a complex number where
is the modulus and
is the angle created on the complex plane.

The modulus of a complex number is the distance from the origin on the complex plane.
where 
Substitute the actual values of a = -5 and b = -5.

Now Find
.
Raise - 5 to the power of 2.

Raise - 5 to the power of 2.

Add 25 and 25.

Rewrite 50 as 5^2 . 2 .

Pull terms out from under the radical.

The angle of the point on the complex plane is the inverse tangent of the complex portion over the real portion.

Since inverse tangent of
produces an angle in the third quadrant, the value of the angle is
.

Substitute the values of
and
.

It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)
