Distance Between Two Points in Coordinate Geometry

Consider the coordinate plane where point A has the coordinates (2, 3) and point B has the coordinates (2, -1). What is the distance between points A and B?

To find the distance between two points, you can use the distance formula: $$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$. In this case, point A has coordinates $(x_1, y_1) = (2, 3)$ and point B has coordinates $(x_2, y_2) = (2, -1)$.
