Best ResponseYou've already chosen the best response.0the equation of the line is\[y=+or\sqrt{1/3}x\]. just by using reduced equation form\[y=mx+b\]. then by solving the system\[\left\{ x ^24x+y^2+3=0;y=mx+b \right\}\] and the line containing the origin and verifying the condition of tangency will give the result
