Question:Intersection of plot with axes

Hello

I have a simple list:

xlist := [150, 250, 500, 800, 1300, 2500, 5000]:

ylist := [.3, .5, .8, 1.0, 1.2, 1.4, 1.6]:

where after i said x:=plot(xlist,ylist);

What I want to do is ask maple" At what x value does the graph intersect with 1.5 on the y axis" or "at what y value does the graph intersect with 3000 on the x axis". 

The data points are just that, I've been looking for commands to ask these questions but have been without luck. You don't need to give me the answer if you can point me to somewhere where this information is written, that would be very helpful!

 

Thank you.
