3. There are toll roads on your way to work each day. You can pay each time at $5/use, or you can purchase a toll pass for $15 which reduces the price to $2/use. How many times do you need to use the toll road before the toll pass is cheaper than pay as you go?

step-by-step explanation:

i am not sure sorry : c

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:

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
