SUMMARY
A linear relationship can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept. This indicates that y varies linearly with x. However, a proportional relationship is more restrictive, defined by the equation y = kx, where k is a constant. Thus, while all proportional relationships are linear, not all linear relationships are proportional due to the presence of the y-intercept.
