How can I solve catenary problems?

If you are on site and you only can get the weight per unit length of cable, the distance between 2 points and the difference in elevation of the said 2 points. How can I solve for the location along the cable for the lowest sag and the tensions exerted at the two points?

what research have you done into this so far ?
there's lots of links on google including at least one site for calculating tension and sag
which probably answers your questions
