Thank you for posting your question here at brianly. I hope the answer will help you. Below is the solution:

or segment from (4,0) to (-4,0), y is always zero because straight segment.
in that case x*y=x*0=0 
and x+y=x+0=x 
if you choose x=4-t where t goes from 0 to 8 you should get 
r(t)=0i+(4-t)j
