Question 697283

{{{ x+4y>8}}} graph it just like equality; find intercepts, plot the points and draw a dashed line because you have > sign which means that all points on a line are excluded from a set of solutions

write it as an equation
{{{ x+4y=8}}}....find {{{x-intercept}}}; set {{{y=0}}}


{{{ x+4*0=8}}}

{{{ x=8}}}...{{{x-intercept}}} is at ({{{8}}},{{{0}}})



{{{ x+4y=8}}}....find {{{y-intercept}}}; set {{{y=0}}}


{{{ 0+4y=8}}}

{{{ y=8/4}}}


{{{ y=2}}}...{{{y-intercept}}} is at ({{{0}}},{{{2}}})




now graph a dashed line and shade everything above the line
