We want to find the intersection of \(x^2+y^2-2x-4y=0~\&~y=-2x+9\)Hi I need to find the the intersection(s) of a line and a cicle. I found a solution using Quadratic formula but how can this be done using matrix/linear algebra??
Hi, Thanks for the reply.Do you want to use linear algebra because you think it will be easier, or because you want to make it harder?
Also, are you assuming you are given the equations as in the example, or the center and radius, or what? I suppose you might be able to use the line through the circle's center perpendicular to the line as part of your work ...
