Replace the Cartesian equation with an equivalent polar equation
x² + y² = 144

In polar coordinates, r ² = x ² + y ², so

x ² + y ² = 144   →   r ² = 144

12² = 144, so this reduces to

r = 12

which represents a circle with radius 12.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
