I'm not too sure how I would do this would i solve the equations simultaneously?

#

^ to prove a line is tangent to a circle

#

Solve normally

#

then show there’s only one solution

#

meaning line has to be a tangent

#

as they interest once

#

okay so i wouldn't need to do the negative reciprocal or anything like that right
