Question 299789
Find the difference between the pair of points. Express your answer in simplest form. (6,-6) and (10,-4)
---------------------------
I'll assume you mean the distance.
{{{d = sqrt(dy^2 + dx^2) = sqrt(2^2 + 4^2)}}}
dy = y2-y1
dx = x2-x1
(Since they're squared, the order does not matter)
{{{d = sqrt(20)}}}
{{{d = 2sqrt(5))}}}
d =~ 4.472
