Question

find the distance between the points $(-10, -4)$ and $(-10, -9.3)$.
______ units

Explanation:

Step1: Identify coordinate type

The points have identical $x$-coordinates ($-10$), so they lie on a vertical line. The distance is the absolute difference of $y$-coordinates.

Step2: Calculate absolute difference

$\vert -4 - (-9.3) \vert = \vert -4 + 9.3 \vert = \vert 5.3 \vert$

Step3: Simplify absolute value

$\vert 5.3 \vert = 5.3$

Answer:

5.3 units
