To determine the location of a point on the plane required the initial benchmark. Initial benchmark is made of two number lines that intersect riel perpendicular at the null point, which is a flat (horizontal) and the other upright (vertical). A horizontal line called the X-axis, and a vertical line called the axis Y. Two mutually perpendicular axes is called a Cartesian coordinate system perpendicular or simply coordinate Kartesius.dalam times inni case will make sustu example program that is associated with point atupun cartesian coordinates of two points, we suppose to calculate the distance from the coordinates of two points A ( x1, y1) and B (x2, y2) and this is the shape of his program by using Overloding in C + +;
