    "Find the equations of the line of intersection of the planes x=5 and y=3."

    I am just not "picturing" this. The way I have solved intersecting planes before was by solving for x in both equations, setting them equal to each other, solving for z, plug that back in and solve for x. Finally, let y=t. I don't know how to apply that to this situation. Parametric equations really confuse me anyway. Would someone be so kind as to give me a hint?

    In the example you gave, you solved for x and z. Here, you've already been given the "solutions" to x and y (without any work). The only thing that's left is z. Instead of letting y=t...

    That sounds way too simple, I guess I was thinkin' too much. 18 semester hours of physics, math, and engineering has my brain fried. Thanks for the help.
