Its an absurd decimal, which I'm pretty sure you don't want but will give to you anyway. Its roughly 0.02631578947...
Answer:
(c)
will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is 
So the slope of the line which is perpendicular to y = 3x+2 will be 
Now (a) Line is given as
its slope is
so it will be not perpendicular
(b) Line is given as
its slope is
so it will be not perpendicular
(c) Line is given as
its slope is
so it will be perpendicular to the line y = 3x+2
(d) Line is given as
its slope is 3 so it will not perpendicular to the line y = 3x+2
