One endpoint of a diameter of a circle

centred on the origin is (-3, 4). Find the

coordinates of the other endpoint of this

diameter.

(a,b)=(3,-4)

Step-by-step explanation:

As you know, center (0,0) is the midpoint of the diameter

Formula for midpoint: midpoint=

lets put (x1,y1)=(a,b) assuming the other end point

(0,0)=((a+-3)/2);(b+4)/2)

Then

For a:  0=(a+-3)/2

0=a=-3

a=3

For b:  (b+4)/2=0

b+4=0

b=-4

Therefore (a,b)=(3,-4)

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
