Question

find the distance between the points (12.2, 18) and (12.2, -11).
____ units

Explanation:

Step1: Identify coordinate type

The points have identical x-coordinates ($12.2$), so they lie on a vertical line. The distance is the absolute difference of y-coordinates.

Step2: Calculate y-coordinate difference

$\vert 18 - (-11) \vert = \vert 18 + 11 \vert$

Step3: Compute final distance

$\vert 29 \vert = 29$

Answer:

29 units
