Question 377548
First graph the line,{{{y=2x-3}}}
.
.
.
{{{graph(300,300,-10,10,-10,10,2x-3)}}}
.
.
.
Now choose a point not on the line. 
({{{0}}},{{{0}}}) is a convenient choice.
Test the inequality.
If the inequality is satisfied, shade the region containing ({{{0}}},{{{0}}}).
If not, shade the region that does not contain ({{{0}}},{{{0}}}).
{{{y>=2x-3}}}
{{{0>=2(0)-3}}}
{{{0>=-3}}}
True, shade the region containing ({{{0}}},{{{0}}})
Since there is an inequality in the inequality, the line itself is also part of the solution region.
