Heyoo. I hope this helps you! If you don’t understand, feel free to ask me anything so I can help. There is a formula that I used to solve it (it is included in the picture and properly labelled).
Keep in mind that it even though I labelled (6,3) as x1 and y1 respectively, you can also label them x2 and y2 and label (8,2) as x1 and y1 and still get the same answer.
