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 \"1\" (its from the slope of \"y=1%2Ax-4\" which is also \"1\").\n" ); document.write( "Also since the unknown line goes through (-3,2), 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-2=1%2A%28x%2B3%29\" Plug in \"m=1\", \"x%5B1%5D=-3\", and \"y%5B1%5D=2\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y-2=1%2Ax-%281%29%28-3%29\" Distribute \"1\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y-2=1%2Ax%2B3\" Multiply
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y=1%2Ax%2B3%2B2\"Add \"2\" to both sides to isolate y
\n" ); document.write( "
\n" ); document.write( " \"y=1%2Ax%2B5\" Combine like terms
\n" ); document.write( "
\n" ); document.write( " So the equation of the line that is parallel to \"y=1%2Ax-4\" and goes through (\"-3\",\"2\") is \"y=1%2Ax%2B5\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So here are the graphs of the equations \"y=1%2Ax-4\" and \"y=1%2Ax%2B5\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " graph of the given equation \"y=1%2Ax-4\" (red) and graph of the line \"y=1%2Ax%2B5\"(green) that is parallel to the given graph and goes through (\"-3\",\"2\")
