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

tresset_1 [31]

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 $\sqrt{2}$
