Chris and his friends are going to the ice cream shop that having a sale on milkshakes. Each milkshake cost
$2.
Write an equation that represents buying any number
of milkshakes (m).
Help plz I will mark u

2xm

Step-by-step explanation:

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

b. they are parallel and will never intersect.
