Graph the inequality on a plane. I do not get how to do these problems, I always get them wrong no matter how many times I try them.
\n" ); document.write( "x+y<3
\n" ); document.write( "----------------------------------
\n" ); document.write( "1st: Solve for \"y\":
\n" ); document.write( "y < -x+3
\n" ); document.write( "------------
\n" ); document.write( "2nd: Graph the boundary: y EQUALS -x+3
\n" ); document.write( "Plot two points and draw a dashed line thru them:
\n" ); document.write( "(0,3),(3,0) for example
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C-x%2B3%29\"$
\n" ); document.write( "------------
\n" ); document.write( "3rd: Since you want y LESS THAN -x+3,
\n" ); document.write( "shade the half-plane BELOW the boundary.
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cy%3C-x%2B3%29\"$
