Let [itex]\ell[/itex] be the line given by [itex]\frac{x-1}{2}=\frac{y+2}{-3}=\frac{z-3}{4}[/itex]. Write down a system of two equations in the three unknowns [itex]a[/itex], [itex]b[/itex], [itex]c[/itex] whose solutions give all planes [itex]ax + by + cz = 1[/itex] in which [itex]\ell[/itex] lies, and solve the system. I can certainly write that [itex]a -2b + 3c = 1[/itex]. I can't figure out how to obtain the second equation.
Thanks
James.
