Scatter plots pairs values on two given variables on each axis to help look at relationships between them. If the variables provided are correlated, the points will fall along a line or a curve. If the correlation if strong the point will hug the line morer. If the data points make a line from the origin (low x and y values to high x and y values) the data points are positively correlated. If the graph starts off with high y-values and continues to low y-values then the graph is negatively correlated.
