What is the distance between the points (3, 0) and (2, -1)?

√2
√13
1
2

The correct answer is: √2

To find the distance between two points on a coordinate plane, we use the distance formula d = √((x2 - x1)^2 + (y2 - y1)^2). In this case, our two points are (3, 0) and (2, -1), and plugging in the values into the formula, we get d = √((2-3)^2 + (-1-0)^2) = √((-1)^2 + (-1)^2) = √(1 + 1) = √2. This means that the distance between these two points is √2 units. Option B, √13, is incorrect because it is the distance between the points (3, 0) and (4, 3), not (3, 0) and (2, -1). Option
