Asked by what is it

Identify the coordinates of the midpoint of PQ⎯⎯⎯⎯⎯ with endpoints P(1,−1) and Q(7,−3).

can someone confirm my answer: 8,-4
Answered by oobleck
M = (P+Q)/2 = ((1+7)/2 , (-1-3)/2) = (4,-2)

If the endpoint is at x=7, how in the world could the midpoint be at x=8?
Always do a sanity check when you think you have an answer.
You just forgot to divide by 2.

No, your answer is correct. 8, -4
