Answer: 2
Step-by-step explanation:
We know that the general intercept form of equation of line is given by :-
, where m is the slope of the line.
The given equation of line : 
Dividing both sides by 3 we get

Comparing the equation to the general intercept form of equation of line , we get
The slope of the line (m)=2
Hence, the slope of the line whose equation is
is 2.
