Understanding Coefficients and Constants

The video tutorial explains the linear expression 2x + 4, focusing on the roles of the coefficient and constant. It identifies the coefficient as the number multiplying the variable, which is 2, and the constant as the standalone number, which is 4. The tutorial then evaluates multiple-choice answers, confirming that the coefficient multiplies the variable by 2 and the constant adds 4 to the expression. Incorrect options are also discussed, emphasizing the correct understanding of the expression's components.
