Use the distance formula: [tex] \sqrt{(x2 - x1)^2 + (y2 - y1)^2} [/tex]
(6, -2), (-2, -12)
[tex] \sqrt{(-2 - 6)^2 + (-12 - -2)^2} [/tex] ⇒ [tex] \sqrt{(-8)^2 + (-10)^2} [/tex]
[tex] \sqrt{64 + 100} [/tex] ⇒ [tex] \sqrt{164} [/tex]
[tex] \sqrt{164} [/tex] = 12.8
The distance between points T and U is 12.8 units.
