Ineed to find the unit rate of $112 in 8 hours

Step-by-step explanation:

We are asked to find the the unit rate of $112 in 8 hours.

To find the unit rate, we will divide $112 by 8 hours as shown below:

Therefore, our required unit rate is $14 per hour.

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

graph of this function as shown below:

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
