Distance Between Two Points in Coordinate Geometry

Given the coordinate points A(2, 3) and B(2, 7), determine the distance between these two points on a coordinate plane. Use the distance formula: $$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$ where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
