\n" ); document.write( "y = mx + b is the slope-intercept form of a line\r
\n" ); document.write( "\n" ); document.write( "m is the slope (the amount of rise divided by the amount of run, also known as (change in y) / (change in x))
\n" ); document.write( "b is the y-intercept (where the line crosses the y-axis, i.e. the y value you get when x=0)\r
\n" ); document.write( "\n" ); document.write( "Parallel lines have equal slope.\r
\n" ); document.write( "\n" ); document.write( "Using the point-slope form, y-y0 = m(x-x0) with m=2, (x0,y0) = (5,-1):
\n" ); document.write( "y - (-1) = 2(x - 5) << point-slope form of the parallel line
\n" ); document.write( "y + 1 = 2x - 10
\n" ); document.write( " y = 2x - 11 << slope-intercept form of the parallel line\r
