Remember the episode where Greg has a crush with his math teacher, and Marcia brings home a girl named Linda. Does anyone know he name of that actress who played her and the tv sitcoms she has been in. She looks very familiar

According to "Bradymania" by Elizabeth Moran, "Linda" was played by a girl named Teresa Warder...that's the episode with
Gigi Perreau as Math Teacher Linda O'Hara, and Wes Parker as
himself (playing her fiance)...

This was episode #17, originally aired Jan 23, 1970.

I don't know what else Teresa has appeared in...
