What is an equation in point slope form for the line perpendicular to..

Answer:
b
Step-by-step explanation:
And since we're perpendicular to y is equal to 3x plus 9, we know the slope of the two lines that are perpendicular
K times 3 is minus 1, so k is minus 1/3,
Only b and c match. Plug in the point negative 6,5.
The answer is b.
