In the expression 4x + 3y, what are the coefficients of x and y?

• A. 3 and 4
• B. 4 and 3
• C. 7 and 1
• D. 6 and 2

Answer: (B)

In the expression 4x + 3y, the term "coefficient" refers to the numerical factor that multiplies a variable. In this case, the coefficients are the numbers directly before the variables x and y. For the variable x, the coefficient is clearly 4, as it is the number that is multiplied by x. Similarly, for the variable y, the coefficient is 3, as it is the number multiplying y. Therefore, the coefficients of x and y in this expression are 4 and 3, respectively. This understanding of coefficients is fundamental in algebra, allowing for accurate manipulation and simplification of expressions.
