Given :
A line 18x - 3y = -45 .
To Find :
The slope of a line parallel to the given line.
Solution :
Simplifying given equation in form of :
y = mx + c.
[tex]3y=18x+45\\\\y=6x+15[/tex]
So, slope of above equation is 6.
Therefore, the slope of a line parallel to the given line is 6.
Hence, this is the required solution.
