Proceeding pro se and informa pauper-is, Shirley Johnson, acting on behalf of her minor daughter, Kioki, appeals the magistrate judge’s dismissal of her harassment suit brought under Title IX of the Education Amendments of 1972, 20 U.S.C. § 1681. Johnson contends, in a single paragraph in the argument section of her appellate brief, that the magistrate judge erred in determining that the defendant’s response to the sexual harassment allegations fell short of the deliberate indifference required for recovery. Johnson’s brief is inadequate to preserve this issue for appeal since she neither refers to the record nor cites legal authority. Fed. R.App. P. 28(a)(9). Accordingly, she has waived this claim. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993) (issues must be properly briefed to be preserved for appeal). In any event, the evidence adduced at trial supports the magistrate judge’s findings. See Davis v. Monroe County Bd. of Educ., 526 U.S. 629, 643, *432 650, 119 S.Ct. 1661, 143 L.Ed.2d 839 (1999).

AFFIRMED.
