How well a regression fits the points

Explanation:

With a R^2 value close to 1, we the regression would fit the points perfectly:

Since the R^2 isn't 1 the points won't fit the line perfectly even though the R^2 value is so high.
Since the R^2 is so high the graph would be accepted. Typically the lower limit is approximately R^2 = 95 for a good graph.
