Since, a line segment TV has endpoints at (2,10) and (18,-18).
We have to determine the length of this line segment.
We will use distance formula for finding this length, which states:
For given points
and

Distance(Length) =

So, length of line segment TV
= (2, 10) and (18,-18)

Length of TV =

=


=

= 32.249 units
= 32.25 units
So, the length of the line segment TV is 32.25 units.
