HELP ASAP!! A merry-go-round is to be built in a park. The center of the structure is required to be equidistant from three support columns located at Q(4,−2), R(2,−4), and S(0,2). What are the coordinates for the location of the center of the merry-go-round?

Answer:
( 1 , -1)
Step-by-step explanation:
A merry-go-round is to be built in a park. The center of the structure is required to be equidistant from three support columns located at Q(4,−2), R(2,−4), and S(0,2).
Let say coordinates for the location of the center of the merry-go-round = (x , y)
Distance of this point from Q , R & S will be equal
(x - 4)² + (y +2)² = (x - 2)² + (y + 4)² = (x - 0)² + (y - 2)²
Equating 1 st & 3rd first
x² + 16 - 8x + y² + 4 + 4y = x² + y² + 4 - 4y
=> 8y - 8x + 16 = 0
=> y - x + 2 = 0
=> x = y + 2
Equating 2nd & 3rd
x² + 4 - 4x + y² + 16 + 8y = x² + y² + 4 - 4y
=> 12y - 4x + 16 = 0
=> 3y - x + 4 = 0
=> x = 3y + 4
Equating x from both
3y + 4 = y + 2
=> 2y = -2
=> y = -1
x = - 1 + 2 = 1
( 1 , -1) are the coordinates for the location of the center of the merry-go-round
