Need help sorting the equations in the right positions. The equation that is shown the variables constants, coefficients, terms, and like terms need to be put in the spot where they go

Given:
7y-3+5y+2
-k-5m+6+8k
8b-9a+c
Required:
We want to shown the variables constants, coefficients, terms, and like terms
Explanation:
1) 7y-3+5y+2
variables : y
constants : -3, 2
coefficients : 7, 5
terms : 7y, -3, 5y, 2
like terms : 7y, 5y
2) -k-5m+6+8k
variables : k, m
constants : 6
coefficients : -1, -5, 8
terms : -k, -5m, 6, 8k
like terms : -k, -5m, 8k
1) 8b-9a+c
variables : b, a, c
constants : --
coefficients : 8, -9, 1
terms : 8b, -9a, c
like terms : 8b, -9a, c
