Equation of perpendicular line
[tex]\\ \sf\dashrightarrow 3y=x-6[/tex]
[tex]\\ \sf\dashrightarrow y=\dfrac{1}{3}x-2[/tex]
Comparing with y=mx+b
Slope of perpendicular line=-3
Passing through (2,-5)
Equation of line in point slope form
[tex]\\ \sf\dashrightarrow y-y_1=m(x-x_1)[/tex]
[tex]\\ \sf\dashrightarrow y+5=-3(x-2)[/tex]
[tex]\\ \sf\dashrightarrow y+5=-x+6[/tex]
[tex]\\ \sf\dashrightarrow x+y-1=0[/tex]
