Question

awarding brainliest! PLEASE SHOW WORK!What are the coordinates of the midpoint of segment whose endpoints are A(-1,9) and B(3,8)? Enter your answers and decimals and if necessary as a coordinate point.

Answer 1

Step-by-step explanation:

$A(-1,9) \\ B(3,8) \\ midpoint \: = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

$x1 = - 1 \\ x2 = 3 \\ y1 = 9 \\ y2 = 8$

$Midpoint = ( \frac{ - 1 + 3}{2} \: , \frac{9 + 8}{2} ) \\ Midpoint = ( \frac{2}{2} ,\: \frac{17}{2} )$

$Midpoint =( 1 , \frac{17}{2} )$

Answer 2

Step-by-step explanation:

A (-1 + 3)/2= 1

B ( 9+ 8)/2= 8.5

answer (1, 8.5)
