Convert the polar coordinates to rectangular form:
 $\left(\sqrt{2},\ -\frac{\pi}{4}\right)$  

• (1, 1)

• (1, -1)

• (-1, 0)

• (-1, -1)

Convert the polar equation to rectangular form:
 $r=7$  

• x² + y² = 49

• x = 7

• x + y = 49

• x² + y² = 7

Convert the polar equation to rectangular form:
 $\theta=\pi$  

• y = x

• x = 0

• y = 0

• tan θ = 0

Convert the rectangular equation to polar form:
 $x=4$  

• r sin θ = 4

• r = 4 csc θ

•  $r=\ \frac{\sec\theta}{4}$  

• r = 4 sec θ
