Question

#2: what is the distance between point d and point e? *

Explanation:

Step1: Find coordinates

Find coordinates of \(D\) and \(E\). \(D(3,1)\), \(E(3, - 2)\).

Step2: Use distance formula for same \(x\) - coordinate

Since \(x\) - coordinates are same (\(x_1=x_2 = 3\)), use \(d=\vert y_1 - y_2\vert\).
\(d=\vert1-(-2)\vert=\vert1 + 2\vert\)

Step3: Calculate absolute value

\(\vert1 + 2\vert=\vert3\vert = 3\)

Answer:

\(3\)
