A line segment on a number line has its endpoints at -9 and 6. Find the coordinate of the midpoint of the segment.. . A. 1.5. B. -1.5. C. 2. D. -3. . Find the coordinates of the midpoint of HX given that H(-1,3) and X(7,-1).. . A. (3,1). B. (0,4). C. (-3,1). D. (-4,0). . please help!
Add
-9 + 6 = -3
Divide by 2
-1.5
2) -1 + 7 = 6 / 2 = 3 ; 3 + -1 = 2 / 2 = 1
(3, 1)
By definition, the midpoint is given by:
\(m = (\frac{x1+x2}{2}, \frac{y1+y2}{2})\)
Part A:
For the line segment we have:
\(m = \frac{-9+6}{2}\)
\(m= \frac{-3}{2}\)
\(m = -1.5\)
Answer:
the coordinate of the midpoint of the segment is:
B. -1.5
Part B:
For line segment HX we have:
\(m = (\frac{-1+7}{2}, \frac{3-1}{2})\)
\(m = (\frac{6}{2}, \frac{2}{2})\)
\(m = (3,1)\)
Answer:
the coordinates of the midpoint of the segment is:
A. (3,1)
