Given parametric liue is(:1+t,2-2t,-1+3t:)Here x <= 1+t=>x-1=1y=2-2t=>x-1=t and z=-1+3t=>y-2=-2t=>z+1=3t=>(y-2)/(-2)=t Hence live is (z+1)/(3)=t(x-1)/(1)=(y-2)/(-2)=(z+1)/(3)=t(1) Hele the equation of plawe is 2x+z=0 As we know that the line (x-x_(1))/(x)=(y-y))/(b)=(z-z_(1))/(c) and plane Ax+By+Cz+d=0 are(a) perpendicular if (a)/(A)=(b)/(B)=(C)/(C)(b)" parcillel if "aA+bB+Cc=0" (C) "Here (a,b,c)=(1,-2,3)and{: ...
