Question

Segment AB is the diameter of circle M. The coordinates of A are (−4,3).
The coordinates of M are (1,5). What are the coordinates of B?

(1) (6,7) (3) (−3,8)

(2) (5,8) (4) (−5,2)

Answer 1

The diameter AB passes thru M and AM=MB and both are radii
From A to M, the x coordinate changes by +5 and the y coordinate changes by +2
Continuing on from M to B with the same changes
Add 5 to 1 for the x coordinate
Add 2 to 5 for the y coordinate
The coordinates of B are (6,7)

Answer 2

how do i show my work for this??
