Question 1026108
.
I don't know how to linear graph

X - y = 8
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
From 

x - y = 8 

you can get 

x-8 = y

by moving y from the left to the right and changing its sign, and
by moving 8 from the right to the left and changing sign.

But x-8 = y is the same as y = x - 8.

Now ask yourself: can you plot / graph   y = x - 8  ?
