Question

try it! 1. refer to the figure shown. how can you find the length of ac?

Explanation:

Step1: Identify coordinates

Point A is at - 3 and point C is at 1.

Step2: Use distance formula on number - line

The distance between two points \(x_1\) and \(x_2\) on a number - line is \(d=\vert x_2 - x_1\vert\). Here \(x_1=-3\) and \(x_2 = 1\), so \(d=\vert1-(-3)\vert\).

Step3: Simplify the expression

\(\vert1-(-3)\vert=\vert1 + 3\vert=\vert4\vert = 4\).
