You can put this solution on YOUR website!
the equation (one of them)for a line is:\r
\n" ); document.write( "\n" ); document.write( "y = mx + b with m being the slope and b being the y intercept..\r
\n" ); document.write( "\n" ); document.write( "if the line is horizontal ie: y = the same number for each pair
\n" ); document.write( "then the slope or m = 0
\n" ); document.write( "if the line is vertical ie: x = the same number for each pair..then the slope is undefined.\r
\n" ); document.write( "\n" ); document.write( "So let's solve the problems:\r
\n" ); document.write( "\n" ); document.write( "y = 6 this is a vertical line so the slope or m = zero and the y intercept (where the line crosses the y axis) is = 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x + 9y = -1...the easiest is to get this in linear form. So substract 4x from both sides
\n" ); document.write( "9y = -4x -1 now divide by 9
\n" ); document.write( "y = -4/9(x) - 1/9
\n" ); document.write( "so slope (m) = -4/9 and the y intercept (b) = -1/9\r
\n" ); document.write( "\n" ); document.write( "Last one:\r
\n" ); document.write( "\n" ); document.write( "y = 3x + 1/5 see if you can do this one yourself!!!!\r
\n" ); document.write( "\n" ); document.write( "hopes this helps\r
\n" ); document.write( "
