{{{x-2y=2}}}

{{{x-2=2y}}}

{{{y=x/2-2/2}}}

{{{y=x/2-1}}}
 
to graph it, you need two points

so, choose values : 
if {{{x=0}}} and if {{{y=0}}} 

if {{{x=0}}}, then {{{y=0/2-1}}}->{{{y=-1}}}

if {{{y=0}}}, then {{{0=x/2-1}}}->{{{x/2=1}}}->{{{x=2}}}

table:

{{{x}}}|{{{y}}}

{{{0}}}|{{{-1}}}

{{{2}}}|{{{0}}}

plot these points and draw a line through


{{{drawing( 600,600, -10, 10, -10, 10,
circle(0,-1,.12),circle(2,0,.12),
locate(0,-1,p(0,-1)),locate(2,0.7,p(2,0)),
 graph( 600,600, -10, 10, -10, 10, x/2-1)) }}}
