Answer:
The answer is
2.8 units
Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-3,1) and (-1,-1)
The distance between them is
[tex] |AB| = \sqrt{ ({ - 3 + 1})^{2} + ( {1 + 1})^{2} } \\ = \sqrt{( { - 2})^{2} + {2}^{2} } \\ = \sqrt{4 + 4} \\ = \sqrt{8} \: \: \\ = 2 \sqrt{2} \\ \: \: \: \: = 2.8284[/tex]
We have the final answer as
2.8 units to the nearest tenth
Hope this helps you
