The distance formula is this:       d    =                                        (                          y              2                        -                          y              1                        )                    2                +                              (                          x              2                        -                          x              1                        )                    2                    , where             (              x        1            ,              y        1            )       are the coordinates of the first point,             (              x        2            ,              y        2            )       are the coordinate of the second point, and d is the distance between the two points.Let&#039;s say (−1,7) is the first point, and (2,12) is the second point Note that it doesn&#039;t matter which one we call the first or second point      d    =                                        (            12            -            7            )                    2                +                              (            2            -                          (              -              1              )                        )                    2                          d    =                  25        +        9                  d    =                  34              ≈    5.83
