WebThis line represents the underlying relationship between the two quantities. When drawing a line of best fit the aim is to keep the distances of all the points from the line to a minimum. Sometimes it is helpful to try to keep the number of points above the line the same as the number of points below the line. Lines of best fit can be used to ... WebWe know that 1965 on the graph is where x=0, and about 41 or 42% of Americans smoked... but we want to know how many Americans smoked in 1945. Even though the graph doesn't show 1945, we can draw the line backwards (to the left of the y-axis) and estimate the y-value from the graph. In the video (at. ) it looks like the y-value is about 51 or 52%.
