Answer:

  x² +y² = 14x

Step-by-step explanation:

Making the usual substitution x = r·cos(θ) and r² = x² +y², we can get there this way:

Substitute cos(θ) = x/r:

  r = 14·x/r

Multiply by r:

  r² = 14x

Substitute for r²:

  x² + y² = 14x

_____

The original equation is shown dotted; the rectangular version is shown as a solid line. The graphs are identical.
