In the xy-coordinate plane, the graph of y =-x^2+9 intersects line l at (p,5) and (t,-7). What isthe least possible value of the slope of l ?A 6B 2C -2D -6E -10 具体计算过程和答案
5=-p^2+9
p^2=4
p=±2
-7=-t^2+9
t^2=16
t=±4
while (2,5) and (4,-7)
slope=(-7-5)/(4-2)=-6
while (2,5) and (-4,-7)
slope=(-7-5)/(-4-2)=2
while (-2,5) and (4,-7)
slope=(-7-5)/(4+2)=-2
while (-2,5) and (-4,-7)
slope=(-7-5)/(-4+2)=6
the answer: A B C D
