Question

find st. need help with this question? get a hint

Explanation:

Step1: Identify coordinates of S and T

S is at - 7 and T is at - 4.

Step2: Calculate the distance ST

Use the formula for distance on a number - line \(d=\vert x_2 - x_1\vert\). Here \(x_1=-7\) and \(x_2 = - 4\), so \(ST=\vert-4-(-7)\vert=\vert-4 + 7\vert=\vert3\vert = 3\).
