Answer:
And then the rectangular coordinates for this case are :
Step-by-step explanation:
We have the following point given 
and we want to conver from polar to rectangular coordinates and we need to use the following formulas:
For this case we have that:
And:
Replacing we got:
And then the rectangular coordinates for this case are :
A proportional relationship is also a direct variation.
The general equation of direct cvariation is
y = kx,
where k is a number.
In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as
y = -x
