Question

what is the length of $overline{fg}$?

Explanation:

Step1: Identify coordinates

The coordinate of point F is 478 and the coordinate of point G is 482.

Step2: Calculate length

The length of a line - segment with endpoints \(x_1\) and \(x_2\) on a number - line is given by \(|x_2 - x_1|\). Here, \(x_1 = 478\) and \(x_2 = 482\), so the length of \(\overline{FG}=482 - 478\).
\(482-478 = 4\)

Answer:

4
