Solve for x- and y-intercepts. Standard form is \"ax%2Bby+=+c\"
\n" ); document.write( "To find the x-intercept, let y = 0 and solve for x.
\n" ); document.write( "To find the y-intercept, let x = 0 and solve for y.
\n" ); document.write( "1) \"8y%2B4x+=+24\"
\n" ); document.write( "\"4x%2B8y+=+24\" Let x = 0.
\n" ); document.write( "\"4%280%29%2B8y+=+24\"
\n" ); document.write( "\"8y+=+24\" Divide both sides by 8.
\n" ); document.write( "\"y+=+3\" This the y-intercept.
\n" ); document.write( "\"4x%2B8y+=+24\" Let y = 0.
\n" ); document.write( "\"4x+%2B+8%280%29+=+24\"
\n" ); document.write( "\"4x+=+24\" Divide both sides by 4.
\n" ); document.write( "\"x+=+6\" This the x-intercept.
\n" ); document.write( "\"graph%28300%2C200%2C-5%2C8%2C-5%2C5%2C%28-1%2F2%29x%2B3%29\"
\n" ); document.write( "2)\"5y%2B10x+=+30\"
\n" ); document.write( "\"10x%2B5y+=+30\" Let x = 0.
\n" ); document.write( "\"10%280%29%2B5y+=+30\" Simplify.
\n" ); document.write( "\"5y+=+30\" Divide both sides by 5.
\n" ); document.write( "\"y+=+6\" Ths the y-intercept.
\n" ); document.write( "\"10x%2B5y+=+30\" Let y = 0.
\n" ); document.write( "\"10x+%2B+5%280%29+=+30\" Simplify.
\n" ); document.write( "\"10x+=+30\" Divide both sides by 10.
\n" ); document.write( "\"x+=+3\" This is the x-intercept.
\n" ); document.write( "\"graph%28300%2C200%2C-5%2C5%2C-5%2C8%2C-2x%2B6%29\"\r
