Question

In 3d graphing, what is the equation of the x-axis and the y-z plane?

Answer 1

You want to plot it in 3d plotter?

Answer 2

No, i'm trying to figure out the equaion of the surface that would make it so the distace from P to the x-axis is four times the distance from P to the yz plane

Answer 3

I know for the x-axis, y=0 and z=0 so x=k but how would I incorporate that into an equation? And the yz plane is just x=0, right? For all values of y and z, x=0?
