Question 1019269
{{{ 3 = 2x - y }}}
First put it in the form:
{{{ y = m*x + b }}} where
{{{ m }}} = slope 
{{{ b }}} = y- intercept
--------------------
{{{ 3 = 2x - y }}}
Add {{{ y }}} to both sides
{{{ y + 3 = 2x }}}
Subtract {{{ 3 }}} from both sides
{{{ y = 2x - 3 }}}
--------------
This says 
slope = 2
y-intercept = -3
---------------
Here's the graph:
{{{ graph( 400, 400, -10, 10, -10, 10, 2x - 3 ) }}}
check:
Find the x-intercept
{{{ y = 0 }}}
{{{ y = 2x - 3 }}}
{{{ 0 = 2x - 3 }}}
{{{ 2x = 3 }}}
{{{ x = 3/2 }}}
This looks right on graph
