Answer

$ \sqrt {130}$ or 11.40 unit

Work Step by Step

To calculate distance between given points (-1, -2) and (-10, 5), we will use distance formula- r = $ \sqrt { (x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2}}$ = $ \sqrt { (-10 - (-1)) ^{2} + (5 - (-2)) ^{2}}$ = $ \sqrt { (-10 +1) ^{2} + (5 +2) ^{2}}$ = $ \sqrt { (-9) ^{2} + (7) ^{2}}$ = $ \sqrt {81 +49}$ = $ \sqrt {130}$ = 11.40 unit
