By visualizing, I know if the y-intercept is on the positive y-axis,
\n" ); document.write( "and the slope is positive, then the x-intercept is on the
\n" ); document.write( "negative x-axis.
\n" ); document.write( "-----------------
\n" ); document.write( "The slope is ( change in y ) / ( change in x )
\n" ); document.write( "The intercepts are (0,4) and (x[1], 0)
\n" ); document.write( " $\"+%28+4+-+0+%29+%2F+%28+0+-+x%5B1%5D+%29+=+2+\"$
\n" ); document.write( " $\"+4+%2F+%28-x%5B1%5D%29+=+2+\"$
\n" ); document.write( " $\"+-x%5B1%5D+=+2+\"$
\n" ); document.write( " $\"+x%5B1%5D+=+-2+\"$
\n" ); document.write( "The x-intercept is (-2,0)
