SUMMARY
The regression equation provided is y=2.3-1(x) with an r² value of 0.78. The coefficient of correlation (r) is definitively -0.88 due to the negative slope of the equation. This negative correlation indicates a strong inverse relationship between the variables x and y, meaning that as x increases, y decreases. The coefficient of correlation ranges from -1 to 1, with negative values signifying a negative relationship.
