Distance Between Two Points Distance Between Two Points Formula(1) Distance between two points on X-axis : The coordinate axes in the coordinate plane can be treated as number lines. If P(x1, 0) and Q(x2, 0) are two points on X-axis, the distance between them is taken as PQ = |x1-x2| ..........(i)(2) Distance between two points on Y-axis: If the points A(0, y1) … [Read more...] about Distance Between Two Points
