Answer:
8 and 1
Step-by-step explanation:
Any equation which can be expressed in terms of a,b, c and so on is algebraic expression.
The term a, b , c ...are variables. They are called so be cause their value can change based on change in condition.
Coefficient are the number with which a variable is multiplied with.
Example
10a+ 20b+c+7d+ 10 is algebraic expression.
The terms which is free of any variable is called constant as its value remains fixed.
In above expression 10 is constant term.
Here term a, b,d are multiplied with 10, 20, and 7 respectively. Thus, these terms are coefficient .
If any term does not explicit coefficient then its coefficient is taken as 1.
This can be explained,
as in above example c does not have any explicit coefficient attached with it
"c" can be also expressed as 1*c as multiplication with does alter the value of variable.

Now in the prblem given
expression: 8a + b + 9
Variable are a , b
constant term is 9
8 is multiplied with variable a. so, 8 is coefficient of a.
b does not have any coefficient thus b coefficient can be taken as 1
as 1*b is equal to b.
Thus, coefficient in expression 8a + b + 9 is 8 and 1.
The coefficients in the expression i.e. 8a + b + 9 should be 8 and 1.
Coefficients in the expression:
A coefficient should be integer i..e written along with a variable or it should be multiplied by the variable. In other terms, a coefficient should be considered as the numerical factor of a term that comprise of constant and variables.
So based on this, we can conclude that The coefficients in the expression i.e. 8a + b + 9 should be 8 and 1.
