Points have the following physical properties:

depth
height
thickness
none
(i just want the answers)

Answer is None.

Step-by-step explanation:

Point is a zero-dimensional mathematical object representing a location in one or more dimensions; something considered to have position but no magnitude or direction.

" In particular, the geometric points do not have any length, area, volume or any other dimensional attribute "

Points have the following physical properties:  

depth

height

thickness

none

Hence the answer to the question is None.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
