<p>Okay I'm going through the Math for the PR right now and there is this one question that I know I got right but they don't have the right answer.</p>

<ol>
<li>What is the slope of the line that contains the points (6,4) and (13,5)?
A. -1/8
B. -1/9
C. 1/7 (it says this one is right but I got -1/7)
D. 1
E. 7</li>
</ol>

<p>No, the slope should be positive. If you draw the graph, you will see the line slope up to the right corner.</p>

<p>I think what you did is you did something like (y2 - y1) / (x1 - x2)</p>

<p>m = (Y2-Y1)/(X2-X1) this means the answer is (5-4)/(13-6)= 1/7</p>
