Answer:

<h2> -7 is the slope.</h2><h2>It intercept Y at 224.</h2><h2>It is proportional.</h2>

Step-by-step explanation:

Lucy pays $224 initially, hence the initial amount of her account is $224.

$7 is deducted each time she visits the club.

Hence after visiting first time, the account will have $$224 - $7 = $217$

If she visits second time, then the account will have $$217 - $7 = $ 210$ .

That is with visiting each time, an amount of multiple of $7 is deducted from the account.

Hence, if we take Y as the amount in the account and X as the number of visiting s, then it can be represented as

$Y = 224 - (7timesX)$ ; X is integers.

In the above equation, the term that is multiplied with X is -7, so -7 is the slope.

If X = 0, then Y = 224. It intercept Y at 224.

With X increasing, Y decreases, hence it is proportional.
