<p>If x<r and y<s then which of the following is true?</p>
<p>I. x+r<y+r
II. x-r<y-r
III. xr<yr</p>
<p>A. I only
B. II only
C. III only
D. I and II only
E. I, II and III</p>
<p>And I got stumped on another question that asks to give the best equation that describes the given scatterplot. Anyone who could tell me how to find the equation of a given scatterplot or how to work with options to find the answers?</p>
<p>If x = y, then none of the statements are true. </p>
<p>For scatterplots, you draw the line of best fit as described here: [Scatterplots</a>, Correlation and the Line of Best Fit …](<a href=“http://www.worsleyschool.net/science/files/scatter/plots.html]Scatterplots”>http://www.worsleyschool.net/science/files/scatter/plots.html). Then find the equation of that line.</p>
<p>I don’t think there’s enough information to answer that question?</p>
<p>i definitely agree with ^</p>
<p>I’m usually not that great at these problems unless i plug in numbers, but for this one…im terrible…i dont see where i can plug in numbers lol…the S really throws me off</p>
<p>Not enough information? The question was asked in October 2009 SAT and that was all the information given there.</p>
<p>Can you double-check that you have typed it out correctly…</p>
<p>WRONG VERSION:</p>
<p>If x<r and y<s then which of the following is true?</p>
<p>I. x+r<y+r
II. x-r<y-r
III. xr<yr</p>
<p>A. I only
B. II only
C. III only
D. I and II only
E. I, II and III</p>
<p>CORRECT QUESTION:</p>
<p>If x<y and r<s then which of the following is true?</p>
<p>I. x+r < y+s
II. x-r < y-s
III. xr<ys</p>
<p>A. I only
B. II only
C. III only
D. I and II only
E. I, II and III</p>
<p>PS The answer is A.</p>
<p>Wouldn’t it be I and III?</p>
<p>No. III would be true if x, y, r, and s had to be positive, but try making y positive and the rest negative.</p>
<p>Ah, I see. Damn, I feel stupid now. I have no idea how I got a 790…</p>
<p>Ah damn!! my bad… I really messed that question up. Xiggi is right. I apologize for the misinformation I may have created. My bad it is.</p>
