The total cost for carpet (y) is proportional to the number of square feet (x) purchased. The cost per square foot is $9. Which equation could represent the total cost for 225 square feet of carpet?

A)
y =
(225)
$9

B)
y =
$9
225

C)
y = $9(225)
Eliminate

D)
y =
1
9
(225)

C

Step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
