You can put this solution on YOUR website!
The way to find intercepts is:
\n" ); document.write( "x-intercept:
\n" ); document.write( "Set y = 0 and solve for x
\n" ); document.write( "---------------------
\n" ); document.write( "y-intercept:
\n" ); document.write( "Set x = 0 and solve for y
\n" ); document.write( "---------------------
\n" ); document.write( " $\"+2x+-+4+=+y+\"$
\n" ); document.write( "x-intercept:
\n" ); document.write( "Set y = 0
\n" ); document.write( " $\"+2x+-+4+=+0+\"$
\n" ); document.write( " $\"+2x+=+4+\"$
\n" ); document.write( " $\"+x+=+2+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "y-intercept:
\n" ); document.write( "Set x = 0
\n" ); document.write( " $\"+2%2A0+-+4+=+y+\"$
\n" ); document.write( " $\"+y+=+-4+\"$
\n" ); document.write( "--------------
\n" ); document.write( "So, now you have 2 points you can plot:
\n" ); document.write( "(2,0) and (0,-4)
\n" ); document.write( "Here's the plot:
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+2x+-+4+%29+\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
