Question 310878
Use the distance formula:
{{{d = sqrt((x[2]-x[1])^2+(y[2]-y[1])^2)}}} where the x- and y-coordinates of the two given points (-4,5) and (2,-5) provide the {{{x[1]}}},{{{y[1]}}},{{{x[2]}}},and{{{y[2]}}} respectively.
{{{d = sqrt((2-(-4))^2+(-5-5)^2)}}}
{{{d = sqrt((6)^2+(-10)^2)}}}
{{{d = sqrt(36+100)}}}
{{{d = 11.66}}}
Line segment AB is 11.66 units long.
