I just want to reccomend desmos, it really helped me with graphing because im not so good at it

But what I got is: 
x-4y=-18
x=-18+4y

Root(-18,0)
Y-intercept: (0, 9/2)
1. first point is x int., when y=0
x-4*0=-18, x=-18
(-18,0)
2. second point, y int, when x=0
0-4y=-18
-4y=-18
y=-18/-4=4.5
(0,4.5)
3. you can choose y=1, then x-4=-18, x=-14 , (-14,1)
or for this graph is
maybe better y=4, x-4*4=-18, x=-2  (-2,4)
x-4y=-18, y=3, x=-6 (-6,3)
