LOS ANGELES — The mother of a fugitive teenager known for using an ‘‘affluenza’’ defense in a deadly drunken-driving case agreed Tuesday to be sent from California to Texas to face a charge.

Tonya Couch, 48, appeared for an extradition hearing in downtown Los Angeles, where she was flown last week after being deported from Mexico. She said very little, answering ‘‘yes’’ when asked if she is the Tonya Couch wanted by the state of Texas.

It’s unclear when she will be sent to the Lone Star State, where prosecutors charged her with hindering the apprehension of a felon. Her next court date in Los Angeles was set for Jan. 19, but authorities in Texas could pick her up at any time, according to the Los Angeles County District Attorney’s Office.

Couch and her son, Ethan, 18, were apprehended last week in Mexico, where authorities believe the pair fled in November as Texas prosecutors investigated whether he had violated his probation in a car crash that killed four.

Ethan Couch is being held at a detention facility in Mexico City after winning a court reprieve that could lead to a weeks- or even months-long legal process in Mexico.
