The graph of the line crosses the x axis when y = 0
\n" ); document.write( "Plug y = 0 into the equation and isolate x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x+5y = 12
\n" ); document.write( "4x+5*0 = 12
\n" ); document.write( "4x+0 = 12
\n" ); document.write( "4x = 12
\n" ); document.write( "4x/4 = 12/4
\n" ); document.write( "x = 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When we plugged in y = 0 and solved for x, we got x = 3.
\n" ); document.write( "So those x and y values pair up to get (x,y) = (3,0)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, the x intercept is (3,0) meaning that the graph crosses the x axis at 3.
\n" ); document.write( "
\n" );
