Question 757303
{{{y=4x/(x-2)}}}

to graph it choose several values for {{{x}}}, calculate {{{y}}}, plot points on a graph and draw a line through:

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

{{{0}}}|{{{0}}}.......{{{y=4*0/(0-2)=0}}}

{{{1}}}|{{{-4}}}.......{{{y=4*1/(1-2)=4/-1=-4}}}

{{{-1}}}|{{{4/3}}}.......{{{y=4*(-1)/(-1-2)=-4/-3=4/3}}}

{{{2}}}|{{{undefined}}}.......{{{y=4*2/(2-2)=8/0=undefined}}}

{{{-2}}}|{{{2}}}.......{{{y=4*(-2)/(-2-2)=-8/-4=2}}}

{{{8}}}|{{{5.33}}}.......{{{y=4*8/(8-2)=32/6=5.33}}}

{{{4}}}|{{{8}}}.......{{{y=4*4/(4-2)=16/2=8}}}

{{{6}}}|{{{6}}}.......{{{y=4*6/(6-2)=24/4=6}}}
