An x-intercept is a point that is on the x axis. Hence, the y coordinate of that point is 0.
\n" ); document.write( " $\"4x-5y=12\"$
\n" ); document.write( "if y=0, then
\n" ); document.write( " $\"4x+-+5%2A0+=+12\"$
\n" ); document.write( " $\"4x+=+12\"$
\n" ); document.write( " $\"x=3\"$
\n" ); document.write( "So the x intercept is the point (3,0)\r
\n" ); document.write( "\n" ); document.write( "Similarly, a y intercept is a point on a y axis. So, the x coordinate must be 0 there.
\n" ); document.write( " $\"4x-5y=12\"$
\n" ); document.write( "if x=0, then
\n" ); document.write( " $\"4%2A0+-+5y+=+12\"$
\n" ); document.write( " $\"-5y+=+12\"$
\n" ); document.write( " $\"y+=+-12%2F5\"$
\n" ); document.write( "So the y intercept is (0, -12/5}}}\r
