Question

centre of the circe is 4,-1 one end of diametre of circe is 9,7 find another end​

Answer 1

HELLO!!

ANSWER:

Another end = (-1,-9)

EXPLANATION:

GIVEN:

(x1,y1) = (9,7)

(x2,y2) = (x,y)

Midpoint=(4,-1)

TO FIND:

x and y

SOLUTION:

Midpoint = ( x1+x2/2 , y1+y2/2 )

(4,-1) = ( 9+x/2 , 7+y/2 )

4 = 9+x /2

9+x = 8

x = 8-9

x = -1

-1 = 7+y/2

7+y = -2

y = -2-7

y = -9

HOPE IT HELPS YOU!!

Answer 2

Solve the 2 equations and you get the values of x and y .
