Answer:
The center of circle D is (-0.5,3)
Step-by-step explanation:
Given the end points of diameter: (-5,8) and (4,-2)
To find: Center of the circle.
Center is in the middle of the diameter. Therefore we have to find the midpoint of the diameter.(refer figure)
Midpoint of a line with end points (x1, y1) and (x2, y2) is given by
( , )
( , )
(-0.5,3)
Hence the center of circle D is ( -0.5,3)
8m+3
Because sum means adding so you add 8m and 3
