The midpoint of a line segment with end points as (10, y1) and (6, 7) is (8, 6). What is the value of y1?
Midpoint formula is (x1 + x2)/2 , (y1 + y2)/2 but I keep getting a wrong answer.

Best ResponseYou've already chosen the best response.0the midpoint formula uses ends to find middle; you got a middle and end mixed up

Best ResponseYou've already chosen the best response.06, 7, y , lets move this to the start at 0 6 6 6  0 , 1 , n ; since you moved 1 to get halfway, move 1 again to get to the end; n = 1+1 = 2 , now move this all back to start at 6 :) 0 , 1 , 2 +6 +6 +6  6 , 7 , 8

Best ResponseYou've already chosen the best response.0its not the "formula", but it is the concept behind finding the middle and extremes

Best ResponseYou've already chosen the best response.1(y + 7) /2 = 6 I solve for y, right^ yes, this is one way to find the answer another way is notice that if you start at one end (6,7) and move (2,1) you get to the mid point (8,6). move the same amount (2,1) from the mid point to get to the other end.
