A line is perpendicular to y = - x-1
and intersects the point (6,9).
What is the equation of this
perpendicular line?

Answer :

Answer:

y=x+3

Step-by-step explanation:

y=-1x-1..... k1=-1

k1*k2=-1 (perpendicular) then

Slope=1=k2

A(6,9) x1 =6,y1 =9

y-y1 =k2(x-x1)

y-9=1(x-6)

y-9=x-6

y=x-6+9

y=x+3
