Tangents are drawn to circle \( x^{2}+y^{2}=1 \) at its intersection points (distinct) with the circle \( x^{2}+y^{2}+ \) \( \mathrm{P} \) \( (\lambda-3) x+(2 \lambda+2) y+2=0 \). The locus of intersection of tangents is a straight line, then the slope of that straight line is. 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
