It's nice to draw a picture with these things, so I'll do that:

So from here, you use the midpoint formula. The midpoint formula is (x1+x2)/2 , (y1+y2)/2. The only tricky part is the order in which is information is given gives you a y-coordinate first, which can easily mess ya up. So that being said, by two x-values are 100 and 200, so I will do (100+200)/2 = 150. The y-values are 50 and 100, so I do (50+100)/2 = 75. So the coordinates of the coffee shop would be (150,75), or 150 feet east and 75 feet north. Again, the information is kinda given backwards, so it might be weird.

I see. I betcha I did it backwards just like I was saying was possible in my explanation :/

75 feet north nd 150 feet east

psymon · Answer

Which was wrong apparently.

anonymous · Answer

I already tired (75,100) are you supposed to write it with the words or in parenthesis/

psymon · Answer

I could be missing something obvious, but I still get (150,75). Depending on what kind of program you're doing homework on, it might be very cranky about how you answer.

see it your formulas right

slide 5

psymon · Answer

It is. But if the answer is still wrong, then Im willing to accept that Im doing a stupid mistake.

anonymous · Answer

I think its supposed to be in ( , ) because the notes they gave me were in parentheses.

anonymous · Answer

i just did it and i got (75,150)
