Find the coordinates of point b on ac such that ab is 2/3 of ac.

(2,-5)

Step-by-step explanation:

For the coordinate of y

;2/3( 1- - 8)

;2/3(9) = 6then you subtract 6 from the y coordinate of A...since its AB

;( 1 - 6 ) = -5

For the coordinate of x

;2/3(-6 - 6)

;2/3(-12) = -8then you do the same thing as above

; ( -6 - - 8 ) = 2

Coordinates of point B are ( 2,-5)

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
