Based on the information given in the question, nothing particularly is true. The line need not be straight, or even a smooth curve. There need not be any points on the line but there need not be any points not on it.
Line of best fit
showing data and seeing if it's closely related or not related at all
either a scatter graph or a line graph xx :)
A trend line is graphed from a linear, exponential, logarithmic or other equation, and trys to fit the sorted data that you have. But it may or may not be correlated. The line of best fit is the trend line that best fits your data, having a high correlation. R closer to 1.
The ratio of a pair of values is always the same. or The scatter plot of the data indicates a straight line with a positive slope that passes through the origin.
Scatter plot line graphs are used:In research to see trendsby Actuaries to predict insurance ratesby economist to predict the economyThe general idea is to derive a trend or general theme for a series of points of data.
Scatter graphs are best. Line graphs are OK if the trend is linear but not much good if the trend is non-linear.

The answer to ts question is....Trend Line.
A line of best fit or a trend line.
Values on the x axis is compared with values on the y axis and the line of best fit indicates a possible trend of the data collated.
Some scatter plot ideas are:Age of a certain car vs. selling pricemeasure of hand vs. measure of footwomens height vs. their weightweekly TV vs.weekly exerciseyears since 1956 vs. winning time
