T = 1200 - 0.06c

A print shop copies and prints documents in large volume for its customers. For a particular copy
machine, the equation above gives the amount of toner, T, in grams, left after making c copies.
How many grams of toner are used per copy?

0.06

Step-by-step explanation:

This is a linear equation y = mx + b.

b, the y-intercept, is 1200.  That's how many grams of toner are in the copy machine when no copies have been made.

m, the slope, is -0.06.  That's the change in T per change in C, or in other words, how many grams of toner are used for each copy.

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

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
