a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present. Scatter plots are similar to line graphs in that they use horizontal and vertical axes to plot data points. However, they have a very specific purpose. Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation .
You should use a scatter plot when you want to show the relationship between an independent and a dependent variable in a manner that is quick and easy to view.
Scatter plot graphs are used in mathematics. They are used to show types of relationships or correlations that are between two sets of data.
A scatter plot

randomness of data
A scatter plot will show the data points on a straight line through the origin, whose slope is the constant of proportionality.
It can showwhether or not there is any relationship between two variables,the nature of the relationship - linear, quadratic, inverse, power etc,precision of relationship: the spread or scatter around the curve of best fit,whether the scatter is constant or changes (heteroscedasticity),presence of outliers,clustering (eg heights v/s weight of adults may show one cluster of points for men and another for women. If so, gender is another relevant variable).
Scatter plots show how much one variable is affected by another,A graph that uses points connected by lines to show how something changes in value
to show the relationship between 2 sets of data
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
The answer to ts question is....Trend Line.
Ideally a mapping, or a scatter plot. Not a function because it should not map one value to many (eg square root). Not the regression coefficient since for an even function it would be 0.
