The y-intercept of a linear equation represents the point at which the line crosses the y-axis. In the given equation, y = 4x + 2, the number that is added to the multiple of x (4x) is the y-intercept. This number is 2, hence the correct answer is B. Option A (4) is the coefficient of x and option C (x) represents the independent variable, neither of which are the y-intercept. Option D (None of the above) is incorrect because the y-intercept does exist in this equation.
