Answer:
The given expression can be written as
y= 5-n----(1)
So,here there are two variables y and n.
So, y + n=5
This is general form of line in two variables .
The general form of line is , ax + by +c=0
And equation of line in slope form, is y= m x +c
Comparing with line 1
Here, Y intercept =5
Slope of line= -1
