Scatter plots show correlation.

Explanation:

Not every graph results in a straight line; some do not have strong correlations (relationship/connection). Scatter plots help determine lines of best fit between plotted points that do not have perfect correlation with one another.

Scatter plots can be used to determine regression equations by plugging in the values to a graphing calculator. The equation will be the line of best fit, and the calculator should also tell you the correlation coefficient that indicates how strong the correlation is.
