I have to find coordinate of point S and I only know that point T is (0,4). Please help explain to me what and how to do this. Thank you so much. I have many more like these too if you want to help me with anymore.

Thank you for the opportunity to help you with your question!

Let's say the coordinates of s=(x,y).....so x+0/2=5....x=10,.....to get y...y+4/2=_8.....y+4=-16....y=-12...so the coordinates of s=(10,-12)....so basically it is (x+×/2, y+y/2) to get mid point coordinates .

Please let me know if you need any clarification. I'm always happy to answer your questions. Kindly ask you to make me your tutor and you will be assured of best results
