Step 1: Locate the coordinates of the endpoints.

             The two endpoints M (2, 1) and N (6, 4). Therefore, (x_1, y_1) =

             (2, 1) and (x_2, y_2) = (6, 4).


Step 2: Plug the corresponding coordinates into the Distance Formula. .

                FORMULA:

                    d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}


                   Endpoints M (2, 1) and N (6, 4).

                  d = \sqrt{(6 - 2)^2 + (4 - 1)^2}


Step 3: Calculate the subtraction in parentheses.

               d = \sqrt{4^2 + 3^3}


Step 4: Square the value in parentheses.

                     d = \sqrt{16 + 9}


Step 5: Add numbers and take out the number under the radical sign.

                     d = \sqrt{25}

                     d = 5


                Hence, the length of AB = 5 units
