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

\n" ); document.write( "
\n" ); document.write( " Since any two parallel lines have the same slope we know the slope of the unknown line is \"4\" (its from the slope of \"y=4%2Ax%2B4\" which is also \"4\").\n" ); document.write( "Also since the unknown line goes through (-6,6), 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-6=4%2A%28x%2B6%29\" Plug in \"m=4\", \"x%5B1%5D=-6\", and \"y%5B1%5D=6\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y-6=4%2Ax-%284%29%28-6%29\" Distribute \"4\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y-6=4%2Ax%2B24\" Multiply
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y=4%2Ax%2B24%2B6\"Add \"6\" to both sides to isolate y
\n" ); document.write( "
\n" ); document.write( " \"y=4%2Ax%2B30\" Combine like terms
\n" ); document.write( "
\n" ); document.write( " So the equation of the line that is parallel to \"y=4%2Ax%2B4\" and goes through (\"-6\",\"6\") is \"y=4%2Ax%2B30\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So here are the graphs of the equations \"y=4%2Ax%2B4\" and \"y=4%2Ax%2B30\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " graph of the given equation \"y=4%2Ax%2B4\" (red) and graph of the line \"y=4%2Ax%2B30\"(green) that is parallel to the given graph and goes through (\"-6\",\"6\")
