Question 99113
to graph this question you first must isolate y from each side
{{{x-2y=6}}}
bring the x to the other side
{{{-2y=6-x}}}
divide by -2
{{{y=(x/2)-3}}}

Repeat the same for the next line
 
{{{x+4y=5}}}
Bring x to the other side
{{{4y=5-x}}}
divide by 4
{{{y=(5/4)-(x/4)}}}

by substituting in your x value into your isolated equations you can find the y coordinate. 

ex.

for the equation {{{y=(x/2)-3}}}
you are given a random x value of 4
place 4 in for x and you get the y value
{{{y=(4/2)-3}}}
{{{y=-1}}}

now plot (4,-1) on your graph, and repeat for other points until you can draw your graph.
