Solved by pluggable solver: Finding the Equation of a Line Parallel or Perpendicular to a Given Line

\n" ); document.write( "
\n" ); document.write( " Remember, any two perpendicular lines are negative reciprocals of each other. So if you're given the slope of \"-4%2F3\", you can find the perpendicular slope by this formula:
\n" ); document.write( "
\n" ); document.write( " \"m%5Bp%5D=-1%2Fm\" where \"m%5Bp%5D\" is the perpendicular slope
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"m%5Bp%5D=-1%2F%28-4%2F3%29\" So plug in the given slope to find the perpendicular slope
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"m%5Bp%5D=%28-1%2F1%29%283%2F-4%29\" When you divide fractions, you multiply the first fraction (which is really \"1%2F1\") by the reciprocal of the second
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"m%5Bp%5D=3%2F4\" Multiply the fractions.
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So the perpendicular slope is \"3%2F4\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So now we know the slope of the unknown line is \"3%2F4\" (its the negative reciprocal of \"-4%2F3\" from the line \"y=%28-4%2F3%29%2Ax%2B2\").\n" ); document.write( "Also since the unknown line goes through (-3,5), we can find the equation by plugging in this info into the point-slope formula
\n" ); document.write( "
\n" ); document.write( " Point-Slope Formula:
\n" ); document.write( "
\n" ); document.write( " \"y-y%5B1%5D=m%28x-x%5B1%5D%29\" where m is the slope and (\"x%5B1%5D\",\"y%5B1%5D\") is the given point
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y-5=%283%2F4%29%2A%28x%2B3%29\" Plug in \"m=3%2F4\", \"x%5B1%5D=-3\", and \"y%5B1%5D=5\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y-5=%283%2F4%29%2Ax-%283%2F4%29%28-3%29\" Distribute \"3%2F4\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y-5=%283%2F4%29%2Ax%2B9%2F4\" Multiply
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y=%283%2F4%29%2Ax%2B9%2F4%2B5\"Add \"5\" to both sides to isolate y
\n" ); document.write( "
\n" ); document.write( " \"y=%283%2F4%29%2Ax%2B9%2F4%2B20%2F4\" Make into equivalent fractions with equal denominators
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y=%283%2F4%29%2Ax%2B29%2F4\" Combine the fractions
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y=%283%2F4%29%2Ax%2B29%2F4\" Reduce any fractions
\n" ); document.write( "
\n" ); document.write( " So the equation of the line that is perpendicular to \"y=%28-4%2F3%29%2Ax%2B2\" and goes through (\"-3\",\"5\") is \"y=%283%2F4%29%2Ax%2B29%2F4\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So here are the graphs of the equations \"y=%28-4%2F3%29%2Ax%2B2\" and \"y=%283%2F4%29%2Ax%2B29%2F4\"
