The distance between two points $(x_1, y_1)$ and $(x_2, y_2)$ in a plane is given by the formula $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$. For points A $(1, -1)$ and B $(8, 1)$, the distance is $d = \sqrt{(8 - 1)^2 + (1 - (-1))^2} = \sqrt{7^2 + 2^2} = \sqrt{49 + 4} = \sqrt{53}$, which is approximately 7.28.
