Question

find the distance between the points (-8.9, 3.3) and (-8.9, -9.9).
units

Explanation:

Step1: Identify the coordinates

The two points are \((-8.9, 3.3)\) and \((-8.9, -9.9)\). Since the \(x\)-coordinates are the same (\(-8.9\)), the distance between them is the absolute difference of the \(y\)-coordinates.

Step2: Calculate the distance

The formula for the distance between two points with the same \(x\)-coordinate \((x, y_1)\) and \((x, y_2)\) is \(|y_1 - y_2|\).
Substitute \(y_1 = 3.3\) and \(y_2 = -9.9\) into the formula:
\(|3.3 - (-9.9)| = |3.3 + 9.9| = |13.2| = 13.2\)

Answer:

13.2
