Solution

The degree of an expression is the greatest power of the variable in any term of the polynomial.
The given expression $x + y - z$ is a polynomial in the variable $x, y a n d z$
The term $x$ has a degree $1$
The term $y$ has a degree $1$
The term $z$ has a degree $1$
Since the highest power of the variable in all terms is the same i.e. $1$
hence, the degree of the polynomial is $1$ .
