What character did Phoebe Cates play in "Fast Times at Ridgemont High"?

Phoebe Cates played the character Linda Barrett in "Fast Times at Ridgemont High." Linda is a friend of Jennifer Jason Leigh's character, Stacy Hamilton, and an object of romantic desire for Judge Reinhold's character Brad Hamilton.

Linda is older than Stacy and fancies herself wiser in the ways of love than her friend, whom she counsels through her relationship with Mark Ratner (played by Brian Backer). The character has achieved enduring renown because of the movie's infamous pool party scene, in which Brad imagines Linda emerging from the pool and removing her bikini top to the iconic sound of The Cars' song "Moving in Stereo."
