Question

What is the distance between points A and B: A(2, -1) B(3, -2)

Answer 1

Answer:  $\sqrt{2}$

The Distance between two points in coordinate geometry can be measured by Distance formula.

Step-by-step explanation:

For two points A and B having coordinates A(x1,y1) and B(x2,y2), the distance can be measured by  D=  $\sqrt{}$(x2-x1)²+(y2-y1)²

So, the distance between the given two points can be measured

Distance = $\sqrt{}$(3-2)²+(-2-(-1))²

            = $\sqrt{}$1²+ (-1)²

            =$\sqrt{}$2

So, the distance between the two points is $\sqrt{2}$
