Why does it make sense to call equations of the form 2,000=20x +10y linear equations?

Step-by-step explanation:

because it's graph will always be a straight line as the values of x increases so does the values of y

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

yes because they have the same amount of green and blur marbles.
