Figure B is a scaled copy of Figure A. What is the scale factor from Figure A to Figure B?

1/3

Step-by-step explanation:

figure a to figure b is a reduction so we do the smaller side divided by the bigger side (use the similar sides on the figures)

5/15 = 1/3

or you could do 11/33 = 1/3

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
