Final answer:

The coefficients in the expression -22 + 3y - 12 are 3 for the variable y. There are three terms in the expression, but -22 and -12 are constants and not coefficients, leaving 3 as the sole coefficient, making the correct answer B.

Step-by-step explanation:

The coefficients in the expression -22 + 3y - 12 are the numerical factors that multiply the variables. In this expression, '3' is the coefficient of variable 'y'. However, '-22' and '-12' are constant terms and do not multiply a variable, so they are not considered as coefficients. The number of terms is the count of distinct monomials that make up the expression. Therefore, we have three terms here: '-22', '3y', and '-12'.

The question is asking for the coefficients and the number of terms in the expression -22 + 3y -12.

The coefficients are the numbers in front of the variables. In this case, the coefficients are -22, 3, and -12.

The number of terms is the number of separate expressions added or subtracted. In this case, there are 3 terms: -22, 3y, and -12.

So the correct answer is A) Coefficients: -22, 3, -12; Number of terms: 3.

The correct answer is B) Coefficients: 3; Number of terms: 3.
