The form of the general point-slope equation is:
\n" ); document.write( "\"+y+=+m%2Ax+%2B+b+\"
\n" ); document.write( "\"+m+\" = the slope of the line
\n" ); document.write( "\"+b+\" = the y-intercept
\n" ); document.write( "-----------------------
\n" ); document.write( "The slope is always m = ( change in y ) / ( change in x )
\n" ); document.write( "In the following formula, \"+y+\" is ANY \"+y+\"
\n" ); document.write( "and \"+x+\" is ANY \"+x+\"
\n" ); document.write( "----------------------
\n" ); document.write( "given the point (-11,-3) and \"+m=-9+\"
\n" ); document.write( "----------------------------------
\n" ); document.write( "\"+%28+y+-%28-3%29+%29+%2F+%28+x+-%28-11%29+%29+=+-9+\"
\n" ); document.write( "This is just ( change in y ) / ( change in x ) = m
\n" ); document.write( "\"+%28+y+%2B+3+%29+%2F+%28+x+%2B+11+%29+=+-9+\"
\n" ); document.write( "\"+y+%2B+3+=+-9%2A%28+x+%2B+11+%29+\"
\n" ); document.write( "\"+y+%2B+3+=+-9x+-+99+\"
\n" ); document.write( "\"+y+=+-9x+-+102+\"
\n" ); document.write( "-----------------
\n" ); document.write( "This is now in the form \"+y+=+m%2Ax+%2B+b+\"
\n" ); document.write( "check: does it go through the point ( -11,-3 )?
\n" ); document.write( "\"+-3+=+-9%2A%28-11%29+-+102+\"
\n" ); document.write( "\"+-3+=+99+-+102+\"
\n" ); document.write( "\"+-3+=+-3+\"
\n" ); document.write( "OK
\n" ); document.write( "Here's a plot of the line:
\n" ); document.write( "\"+graph%28+400%2C+400%2C+-16%2C+6%2C+-120%2C+20%2C+-9x+-+102+%29+\"
\n" ); document.write( "
\n" ); document.write( "
