The question is:  In the xy-coordinate plane, the graph of x = y squared - 4  intersects line \"l\" at (0,p) and (5,t).  What is the greatest possible value of the slope of \"l\"?   When I plugged in the p and t coordinates to get the full coordinates, I got a slope of 1/5, so I thought maybe -5 would be the slope of an intersecting line.  Can someone help?  Thanks. </SPAN>\n" );
