The y-intercept of the line y = 3x is 0. In slope-intercept form y = mx + d, the constant d represents the y-intercept where the line intersects the vertical axis. Since the line passes through (0, 0), its y-intercept is 0. Geometrically and practically, it indicates that at the initial state when x = 0, the quantity y begins at zero.
