\n" ); document.write( "if you're solving an equation and the slope is zero what is the x-intercept?
\n" ); document.write( "ex: y= -4
\n" ); document.write( " i know that the y-intercepty = -4
\n" ); document.write( "slope = 0
\n" ); document.write( "but i can't figure out what the x intercept would be by lugging 0 in for y. 0= -4 doesn't make sense.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Think about it!!!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "What is the x-intercept? This is the point at which the line-graph intersects the X-AXIS. Now, as a slope of 0 is a horizontal line that's PARALLEL to the x-axis (the x-axis is also a horizontal line), it will NEVER intersect the x-axis. Thus, THERE IS NO x-intercept.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This means that for any line that has a slope of 0, there is NO X-INTERCEPT. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now, the coordinates of x for any zero-slope equation is ALL REAL NUMBERS, such as (0, 4), (1, 4), (1,300, 4), etc. Taking any of these 2 coordinate points, you will get a numerator of 0, and regardless of the denominator, the slope will be 0 because the numerator is 0 (see below).\r

\n" ); document.write( "\n" ); document.write( "(0, 4); (1, 4)
\n" ); document.write( "\"%284+-+4%29%2F%281+-+0%29\" = \"0%2F1\" = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(0, 4); (1,300 4)
\n" ); document.write( "\"%284+-+4%29%2F%281300+-+0%29\" = \"0%2F1300\" = 0\r
\n" ); document.write( "
