\n" ); document.write( "The x-intercept always occurs when y = 0.
\n" ); document.write( "This is where the curve either touches the x axis, or crosses over the x axis.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-6x+9y = -18
\n" ); document.write( "-6x+9*0 = -18
\n" ); document.write( "-6x = -18
\n" ); document.write( "x = -18/(-6)
\n" ); document.write( "x = 3
\n" ); document.write( "The x-intercept is located at (3,0)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Below is a graph to verify the answer.
\n" ); document.write( "Note that -6x+9y = -18 solves to y = (2/3)x-2
\n" ); document.write( "
\n" ); document.write( "GeoGebra and Desmos are two of many options if you need a graphing calculator.
\n" ); document.write( "Or you can go old-school with something like a TI83.\r
