Question

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

Explanation:

Step1: Identify coordinates

The coordinate of point S is 7 and the coordinate of point T is 8.

Step2: Use distance formula on number - line

The distance between two points on a number - line is given by \(d=\vert x_2 - x_1\vert\). Here, \(x_1 = 7\) and \(x_2 = 8\), so \(d=\vert8 - 7\vert\).

Step3: Calculate the result

\(\vert8 - 7\vert=1\).
