Answer
$D = \sqrt {116}$
See graph below.
Work Step by Step
Given P (-2, -1, 0) and Q (-12, 3, 0), the question asks for a graph of the two points and the distance between them.
See graph below (graphed with GeoGebra)
The distance between the two points is determined by the distance formula:
$D = \sqrt {(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2 }$
$D = \sqrt {(-12 - (-2))^2 + (3 - (-1))^2 + (0 - 0)^2 }$
$D = \sqrt {100 + 16 + 0}$
$D = \sqrt {116}$
