We need to identify the term , like terms , coefficients and constants
For the given :

The terms are :
7j , -11 k , k , -9
so there are four terms, the separation between them is the sign (+) or the sign (-)
the like terms are : (-11 k ) and ( k )
Coefficients are :
7 the coefficient of the term ( 7j )
-11 the coefficient of the term (-11 k )
1 the coefficient of the term ( k )
The constants are the numbers with out variables
there is one constant = -9
