If point B is symmetric to A(4, -1) with respect to the bisector of the first quadrant, then B is at (-1, 4)
Length AB =√ (4--1)² + (-1-4)²
= √ 5² + (-5)²
= √ 25 + 25
= √50
= 2√5
Or 4.47
Length AB =√ (4--1)² + (-1-4)²
= √ 5² + (-5)²
= √ 25 + 25
= √50
= 2√5

Step-by-step explanation:
If point B is symmetric to A(4, -1) with respect to the bisector of the first quadrant, then B is at (-1, 4)
Length AB =√ (4--1)² + (-1-4)²
= √ 5² + (-5)²
= √ 25 + 25
= √50
= 2√5
