A coefficient in a linear equation is a number that multiplies a variable. It is not the same as the slope of the line (choice A), which is the rate of change of the dependent variable with respect to the independent variable. It is also not a number that is added to the y-value (choice C) or the x-value (choice D), as these are simply the coordinates on the x and y axes where the line intersects. Therefore, the only correct answer is choice B, which correctly defines a coefficient as a constant in the equation.
