Question

find the length of the fish model shown.
options: 10 units, 9 units, 8 units, 7 units

Explanation:

Step1: Identify x - coordinates of endpoints

The left endpoint of the horizontal line (representing fish length) is at \( x = 1 \), and the right endpoint is at \( x = 10 \).

Step2: Calculate the distance

The length of a horizontal line segment with endpoints at \( x_1 \) and \( x_2 \) is \( |x_2 - x_1| \). So, \( |10 - 1| = 9 \) units.

Answer:

9 units (corresponding to the option "9 units")
