<p>If this helps I am doing this practice problem from the 2007-08 SAT official practice test. Anyway I can't figure out this problem and I am hoping someone can explain it to me. </p>

<p>Chart: x y

<strong>|</strong>

(0, 100)

(1,99)

(2, 96)</p>

<p>Question: Which of the following equations describes y in terms of x for all ordered pairs in the table above?</p>

<p>(A) y=100-x²

(B) y=100-x

(C) y=100-2x

(D) y=100-4x

(E) y=100-100x</p>

<p>Any help would be greatly appreciated! Also if the chart doesn't makes sense just let me know :)</p>
