Question

A line segment is drawn from (1, 6) to (3, 6) on a coordinate grid. Which answer explains one way that the length of this line segment can be determined? Subtract 6 – 1. Add 6 + 1. Subtract 3 – 1. Add 3 + 1.

Answer 1

Subtract 3-1

Step-by-step explanation

The given line segment has endpoints at (1,6) to (3,6).

This line is a horizontal straight line because the y-coordinates of both points are the same.

We can therefore use the number line method to find the length of this line segment.

Using this method, we subtract the initial x-value from the terminal x-value.
