What is the length of the line segment AB with A(2,7) and B(-3,-12)?

Given the line segment AB such that A(2,7) and
B(-3,-12)

We need to find the length of the line
AB.

Then, we will use the distance between two points
formula to find the length.

We know
that:

D = sqrt( x2-x1)^2 +
(y2-y1)^2

==> l AB l = sqrt[ (-3-2)^2 + (-12-7)^2
]

                 = sqrt[ (25 +
361)

                 = sqrt(386) =
19.65

Then, the length of the line segment AB
is 19.65 units ( approx.)
