Question 110406
The formula is {{{d = sqrt((y[2] - y[1])^2 + (x[2] - x[1])^2)}}}
given the points ({{{x[1]}}}, {{{y[1]}}}) = (-3,-2)
and ({{{x[2]}}}, {{{y[2]}}}) = (1,4)
{{{d = sqrt((4 - (-2))^2 + (1 - (-3))^2)}}}
{{{d = sqrt( 6^2 + 4^2)}}}
{{{d = sqrt( 36 + 16)}}}
{{{d = sqrt(52)}}}
{{{d = 7.211}}} answer
