Question: How do I plot two intersecting lines in space with normal axes?

I want to plot this graph with maple. http://img843.imageshack.us/img843/5300/graphh.jpg The lines are: a) x=2t+3; y=5t-2; z=-t+1 b) x=-2t+7; y=t+8; z=2t-1. I tried to plot the first line with spacecurve, but I don't now how to plot the two lines together.Also I couldn't plot the z axes in the vertical position. spacecurve([2*t+3,5*t-2,-t+1],t=-10..10,axes=normal, labels=[x,y,z],scaling=constrained); Is there a way to find and represent on the intersecting lines the intersection point? Thanks.
