To graph the equation y=4x+1, we just find two points that exist, plot them, and draw a straight line that goes through them.
Let's try x=0:

One point on the line is (0,1)
Let's try x=1:

Another point is (1,5).
Now, plot these two points and draw a line through them.
5-(n-4)=3(n+2)
5-n+4=3n+6
9-n=3n+6
3=4n
n=3/4
