L1: y = 2/5x - 3
\n" ); document.write( "---
\n" ); document.write( "line parallel to L1 and through point (5, 4)
\n" ); document.write( "parallel lines have equal slope:
\n" ); document.write( "m = 2/5
\n" ); document.write( "---
\n" ); document.write( "use the point-slope form:
\n" ); document.write( "point = (5, 4)
\n" ); document.write( "slope = 2/5 = 0.4
\n" ); document.write( "---
\n" ); document.write( "to solve the linear equation, plug this:
\n" ); document.write( "5 4 0.4
\n" ); document.write( "into the \"Point-Slope form: x1 y1 m\" input box of this solver:

\n" ); document.write( "the slope-intercept form:
\n" ); document.write( "y = 2/5x + 2

\n" ); document.write( "line perpendicular to L1 and through point (5, 4)
\n" ); document.write( "perpendicular lines have negative reciprocal slopes:
\n" ); document.write( "m = -5/2 = -2.5
\n" ); document.write( "---
\n" ); document.write( "use the point-slope form:
\n" ); document.write( "point = (5, 4)
