The property that justifies Bianca's first step is the **associative property of addition**.
The associative property of addition states that the way in which numbers are grouped in an addition problem does not affect the sum. In this case, Bianca is regrouping the expression by adding 4 and 1 together first.
Therefore, the correct answer is **associative property of addition**.
