If A (00) and B (8 .2) what is the length of ab?

To find the length of the line segment AB between the points A(0, 0) and B(8, 2), you can use the distance formula: ( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ). Substituting the coordinates, we have ( d = \sqrt{(8 - 0)^2 + (2 - 0)^2} = \sqrt{64 + 4} = \sqrt{68} ). Therefore, the length of AB is ( \sqrt{68} ), which simplifies to ( 2\sqrt{17} ).
