Question

Find the distance between these points. r(-1, 0), s(8, 6)1-√(26)2-√(85)3-3√(13)

Answer 1

distance between two points, d, is given by
$d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }$
where: (x1, y1) = (-1, 0) and (x2, y2) = (8, 6)
$d= \sqrt{ ( 8 - (-1)) ^{2} + (6 - 0) ^{2} } \\ d= \sqrt{ (9)^{2} + 6^{2} } \\ d= \sqrt{81+36} \\ d= \sqrt{117} \\ d=10.8 \ units$
