Graph of data points with a positive correlation: y = _____________

Response: y = 20/3 x + 50

(This equation represents a line with a positive slope, which is characteristic of a positive correlation in a scatterplot.)

Graph of data points with a negative correlation: y = _____________

Response: y = -11/3 x + 95

(This equation represents a line with a negative slope, which is characteristic of a negative correlation in a scatterplot.)

Graph of data points with no correlation: y = _____________

Response: y = x

(This equation represents a line with a slope of 1, which is characteristic of a scatterplot with no discernible correlation between the data points.)
