Question

The distance between (2, 0) and (5, -1) is: 9. 0. 10. mula1" title=" \sqrt10" alt=" \sqrt10" align="absmiddle" class="latex-formula">

Answer 1

Distance = square root ((x2 - x1)^2 + (y2 - y1)^2)
(2,0)...x1 = 2 and y1 = 0
(5,-1)..x2 = 5 and y2 = -1
sub and solve
d = sqrt ((5 - 2)^2 + (-1 - 0)^2)
d = sqrt ((3^2) + (-1^2))
d = sqrt (9 + 1)
d = sqrt 10 <==
