Question

f point C is the midpoint of AB , what is the coordinate of point B?

Answer 1

use the midpoint formula
\[\frac{ x _{2}+x _{1} }{ 2 }, \frac{ y _{2} +y _{1}}{ 2 }\]
and put in the values that you do know to solve for the unknown values

Answer 2

i did that and i got ( 3/2,-1)

Answer 3

the answer is actually (0, -7)

Answer 4

also, you can see that from point a to point c, you down 2 units and 3 units to the right. if you go down 2 units and 3 units to the right from point c, you arrive at (0, -7)

Answer 5

got it?

Answer 6

yes f point C is the midpoint of AB , what is the coordinate of point B?

Answer 7

let's say coordinate of C is (x,y ) then
\[-3=\frac{ (x+(-6)) }{ 2 }=\frac{ x-6 }{ 2 } \] similarly \[-5=\frac{ (y-3) }{ 2 }\] solve for x and y :)

Answer 8

it is known as mid point formula

Answer 9

i got 7.12

Answer 10

x=0 and y= -7

Answer 11

@edwardk is it okay?

Answer 12

yeah B is (0, -7)
