When is work said to be done?

If the work done by a body in application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 5 units. Also, send from the graph the work done when the distance travelled by the body is 2 units.

If the work done by a body in application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 5 units. Also, send from the graph the work done when the distance travelled by the body is 0 units.
