Question 105810

{{{8x+9y<0}}}

first, find a graph of {{{8x+9y=0}}} to see the point where this finction is equal to {{{0}}}

as you will see on the graph, the line goes through {{{0,0}}}, and it is decreasing

for all {{{x}}} where {{{x>0}}} and {{{x= infinity}}}, {{{y}}} will be < then 0,
so, shade the area between x-axis and line to the right from 0 (excluding 0)
