## Elementary Geometry for College Students (5th Edition)

C(4,$\frac{-5}{2}$)
Points A and B have symmetry with respect to point C. To find the coordinates of C given the points: A(3,-4) and B(5,-1) C is the mid point of A and B M=($\frac{x1+x2}{2}$, $\frac{y1+y2}{2}$) C = ($\frac{3+5}{2}$, $\frac{-4-1}{2}$) C(4,$\frac{-5}{2}$) Therefore the coordinates of B(4-a,6-b)
