A line graph represents how a measured quantity changes across an ordered sequence, such as days, months, or repeated observations, by pairing each input with a numerical output and plotting the resulting points on labeled, equally spaced axes. The points are connected to show increases, decreases, and patterns of change; the vertical scale must use consistent intervals, and the graph should not imply values between observations unless the context supports that interpretation.
