Question 29599
{{{ 4x+2y=8 }}}  many ways to do this ...
first solve for x ... 
{{{ 4x+2y=8 }}} subtract 2y
{{{ 4x=8-2y }}} divide by 4
{{{ x=-1y/4 + 2 }}} x-intercept is 2
then solve for y ...
{{{ 4x+2y=8 }}} subtract 4x
{{{ 2y=-4x+8 }}} divide by 2
{{{ y=-2x+4 }}} y-intercept is 4

plot these two points on your coordinate plane and draw the line between them.
