Tangents are drawn to circle x^2+y^2=1 at its intersection points (distinct) with the circle

Tangents are drawn to circle x^2+y^2=1 at its intersection points (distinct) with the circle

Tangents are drawn to circle x^2+y^2=1 at its intersection points (distinct) with the circle x^2+y^2+(lambda-3)x+(2lambda+2)y+2=0 The locus of intersection of tangents is a straight line, then the slope of that straight line is. #tangents #jeemains #jeeadvance
