In the expression 4x - 3y + 7, what is the coefficient of y?

• A. -3
• B. 3
• C. 7
• D. 0

Answer: (A)

In the expression 4x - 3y + 7, the term that involves y is -3y. The coefficient of a variable in an algebraic expression is the numerical factor that multiplies that variable. In this case, the coefficient of the y term is -3, which is the number directly in front of y in the term -3y. Identifying coefficients is a fundamental skill in algebra, as it helps to understand how each component of the expression contributes to its overall value. Since -3 is the number associated with y, it signifies that y is being subtracted in this expression, hence the coefficient is -3. This is why the correct answer is -3.
