Question

Find the centre of a circle if the end point of the diameter are A(-5,7) and B(-3,-11)

Answer 1

(-4,-2)

Step-by-step explanation:

R(x,y) = (x1 + x2 )/ 2, (y1 + y2) / 2

Step-by-step explanation:

R(x,y) = (-5 + -3) / 2 , (7- 11)/2

= (-8 / 2 , -4 / 2 )

= (-4 , -2)

hope it helps.

Answer 2

Answer:

R(x,y) = (x1 + x2 )/ 2, (y1 + y2) / 2

Step-by-step explanation:

R(x,y) = (-5 + -3) / 2 , (7+ 11)/2

= (-8 / 2 , 18 / 2 )

= (-4 , 9)
