Question 76905: Help! I'm stuck. 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.
