Parallel lines have equal slope.
\n" ); document.write( "---
\n" ); document.write( "Given the line L1 in slope-intercept form: y = 5x + 4
\n" ); document.write( "its slope is: 5
\n" ); document.write( "---
\n" ); document.write( "To find a line L2 parallel L1, and passing through the point p2 = (-4, 3),
\n" ); document.write( "use the point-slope form: y - y1 = m(x - x1)
\n" ); document.write( "---
\n" ); document.write( "y - 3 = 5(x - -4)
\n" ); document.write( "y - 3 = 5x + 20
\n" ); document.write( "y = 5x + 20 + 3
\n" ); document.write( "---
\n" ); document.write( "Answer, an equation for line L2 is:
\n" ); document.write( "y = 5x + 23
\n" ); document.write( "---
\n" ); document.write( "Check the work by plugging-in point p2 into the equation:
\n" ); document.write( "---
\n" ); document.write( "3 = 5(-4) + 23
\n" ); document.write( "3 = -20 + 23
\n" ); document.write( "3 = 3
