Question 1085865

{{{9y+5x>=9y-20}}}

it in {{{y=mx+b}}} means solve for {{{y}}}

in your case we have {{{9y}}} on both sides which cancel each other, so

{{{cross(9y)+5x>=cross(9y)-20}}}

{{{5x>=-20}}}

{{{x>=-20/5}}}

{{{x>=-4}}}-> so, you have solution set for {{{x}}}: [{{{-4}}}, {{{infinity}}})

but, for {{{9y+5x>=9y-20}}} there is no solution and there is no {{{x-intercepts}}}
