Answer:
The property shown in matrix addition given is "Additive Inverse Property"
Explanation:
First of all lets define what a matrix is.
A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.
There are several addition properties for matrices.
One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.
Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.
![\left[\begin{array}{ccc}-6&15&-2\end{array}\right] + \left[\begin{array}{ccc}6&-15&2\end{array}\right] = \left[\begin{array}{ccc}0&0&0\end{array}\right]](https://img.qammunity.org/2021/formulas/mathematics/college/q1rmd7shg506ub8y1ojzdwwanbzgkspfoz.png)
Hence,
The property shown in matrix addition given is "Additive Inverse Property"
