Answer:
The answer is 3.2 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
A(0,-1) and B(-1,2)
We have
[tex] |AB| = \sqrt{( {0 + 1})^{2} + ({ - 1 - 2})^{2} } \\ = \sqrt{ {1}^{2} + ( { - 3})^{2} } \\ = \sqrt{1 + 9} \\ = \sqrt{10} \: \: \: \: \: \\ = 3.16227766...[/tex]
We have the final answer as
3.2 units to the nearest tenth
Hope this helps you
