Alyssa is buying miniature cars. she wants to buy 17 cars total for a big race she and her friends are having. silver cars are $5 dollars each. red cars are $7 dollars each. if she spends $111, how many red cars did she buy? part a: write 2 equations to represent the situtation. (1 point using the correct variables, 1 point for the correct equation – each equation) 4 points total let s = silver car let r = red car part

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
