'-3' is the co-efficient of 'y'. The number attached to the variable is the co-efficient.
A coefficient of a variable is the numeral right next to the variable in question. So in the expression 8-3y+1 the 3 (or is it -3? I'm not sure) is the coefficient of y.

b + 1 is b plus 1 as an algebraic expression.
The expression given is 5 - mn - n. In this expression, the second term is -mn. The coefficient of the second term is -1, as it is understood that when a variable is written without a coefficient, it is considered to have a coefficient of 1.
In the expression 7h + 3, the coefficient is 7, which is the numerical factor of the variable h. The constant is 3, which is a term without a variable attached to it. Coefficients and constants are essential components in algebraic expressions and equations, helping determine the value of the expression based on the variables involved.
2m + 1
It is an expression and can be simplified to: 3d+f+1
