Question

Find the midpoint between each (8, -9) and (8, 5)

Answer 1

( 8 + 8 ) / 2 = 8;  ( - 9 + 5 ) / 2 = -2 => ( 8, -2 ).

Answer 2

`The\ formula\ of\ midpoint\ between\ (x_1;\ y_1)\ and\ (x_2;\ y_2)\\\\\left((x_1+x_2)/(2);\ (y_1+y_2)/(2)\right)\\\\===================================\\(8;-9);\ (8;\ 5)\\\\\left((8+8)/(2);\ (-9+5)/(2)\right)\to\left((16)/(2);\ (-4)/(2)\right)\to\fbox{(8;-2)}`
