Answer:
First graph = positive correlation
Second graph = no correlation
Third graph = positive correlation
Fourth graph = negative correlation
Step-by-step explanation: Correlation is the measure of how two or more variables are related to one another. Regarding the first and third graphs, the "y" variable tends to increase as the "x" variable increases, so the points seem to be going in an upward direction; therefore, these graphs represent a positive correlation. Regarding the fourth graph, the "y" variable tends to decrease as the "x" variable increases, so the points seem to be going in an downward direction; therefore, this graph represents a negative correlation. Regarding the second graph, the "y" variable tends to stay somewhat the same as the "x" variable increases, so the points seem to be going neither upwards nor downwards; therefore, this graph has no correlation.
