Transform the polar equation to an equation in rectangular coordinates. 
r=4

• x² + y²=16 ; circle, radius 4, center at pole

• x²+y²=4 circle, radius 2, center at pole

• x² - y²=16 ; circle, radius 16, center at pole

• y=4, 4 units above pole

Transform the polar equation to an equation in rectangular coordinates.

• y=4, horizontal line 4 units above pole
