Understanding Coefficients and Constants

The video tutorial explores the linear expression 2x + 3, focusing on understanding the role of the coefficient. It identifies the coefficient as 2, which multiplies the variable x, and distinguishes it from the constant 3. The tutorial then evaluates various answer choices to determine the correct effect of the coefficient on the expression, concluding that the coefficient multiplies the variable by 2.
