Question

If point C is the midpoint of , what is the coordinate of point B?
Answer

(–3, 3)

(–2, 1)

(–4, 4)

(–4, 1)

Answer 1

the midpoints are found by averaging the x and y values then


1 = (5 + x)/2 4 = (5 + y)/2

2 = 5 + x 8 = 5 + y

solve to find x and y which are the coordinates of B
hope this helps

Answer 2

umm i still dont get it :(

Answer 3

5 + ? = 8 what is the value of the ?

Answer 4

let the vertices of b be x,y then by midpoint formula...
