Just as money doesn't by happiness for individuals, the two don't necessarily go together for countries either. However the scatter plot does show a relationship between a country's annual per capita income and the percentage of people in that country who call themselves "happy." Draw a line that fits the data so that the spread of the data points around the line is as small as possible. Use the coordinates of two points along your line to write the slope-intercept form of its equation. Express the equation in function notation and use the linear function to make a prediction about national happiness based on per capita income.

Definition Definition Representation of the direction and degree of correlation in graphical form. The grouping of points that are plotted makes it a scatter diagram. A line can be drawn showing the relationship based on the direction of points and their distance from each other.
