The distance between the points (-1,7) and (-11,-15) has to be determined.

Use the distance formula that gives the distance between the points `A(x_1, y_1)` and `B(x_2, y_2)` as `D = sqrt((x_2-x_1)^2+(y_2-y_1)^2)`

The distance between (-1,7) and (-11,-15) is `sqrt((-11+1)^2+(-15-7)^2)` = `sqrt(100+484)` = `sqrt584` = `2*sqrt 146 ~~ 24.16`

The exact distance between the points (-1,7) and (-11,-15) is `2*sqrt 146` and the approximate distance is `24.16` units
