<p>Choices A and B are both possible. Here are the points to prove it. (-10,5) and (1,-17) for A. ( for B.</p>

<p>B is said to be the correct one.</p>

<p>How can A be (1,-17)? It says that absolute value of 1 must be greater than absolute value of -17…</p>

<p>(1,-17) is point B. So the slope is -2, which is Answer choice A.
(1,-17) works because in the problem it says the abs. val of POINT A. No requirements for Pt B</p>

<p>nevermind didnt read point B</p>

<p>Slope of AB is r/p but |p|>|r|.</p>

<p>That eliminates A and E. AB clearly has a negative slope, so the only possible choice left is B.</p>

<p>the line segment with (-10,5) and (1,-17) doesn’t go through the origin. so you must use (0,0) and point A to find the slope, not a made-up value for B</p>

<p>If abs(p) is greater than abs(r) and the line passes through the origin, then the gradient must be smaller than 1. It is negative because it’s downward sloping. Hence choice B.</p>

<p>You don’t need to substitute any values. The information given is sufficient.</p>

<p>o ok i get it now thanks crazybandit and sci ur smart</p>
