Question

Acellus

Answer 1

Answer:

$AB = 3.6$

Step-by-step explanation:

Given

The attached graph

Required

Distance AB

From the graph:

$A = (-2,1)$

$B = (1,-1)$

The distance is:

$AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

$AB = \sqrt{(-2 -1)^2 + (1- -1)^2}$

$AB = \sqrt{(-2 -1)^2 + (1+1)^2}$

$AB = \sqrt{13}$

$AB = 3.6$
