Answer:
see below
Step-by-step explanation:
The points at the corners of the given figure are ...
(0, 0), (0, 4), (3, 4), (3, 0)
When the figure is scaled by a factor of 1/3, each of the coordinates is multiplied by 1/3:
(0, 0), (0, 4/3), (1, 4/3), (1, 0) . . . . . points scaled by 1/3
When the figure is scaled by a factor of 3/2, each of the coordinates is multiplied by 3/2:
(0, 0), (0, 6), (9/2, 6), (9/2, 0) . . . . . . points scaled by 3/2

The points that are on your list are shown in bold above.
Answer:
Option B is correct.
direct variation; k = 5/2
Step-by-step explanation:
The Direct variation says:
then the equation is of the form: ......[1] where k is the constant of variation.
From the given table:
Consider x = -2 and y = -5
Substitute these in [1] to solve for k;
or
5 = 2k
Divide both sides by 2 we get;
⇒ the equation becomes:
Check:
Take x = 4 and y = 10;
10 = 10 True
Therefore, the direct variation ; best describe the function represented by the table
