"Webb27 dec. 2016 · A curve is showing its path. But in geometry, a line is strictly straight. A curve is a generalization of line. As, in mathematics, the curved line is a path that need not to be necessarily bent. This implies that a curve may be straight path. Thus a curved line may be a straight path or bent. So, a curve is a generalization of a straight line. " - Shape of valley curve
