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 \"-3%2F2\" (its from the slope of \"y=%28-3%2F2%29%2Ax%2B5%2F2\" which is also \"-3%2F2\").\n" ); document.write( "Also since the unknown line goes through (0,-1), 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( " \"y%2B1=%28-3%2F2%29%2A%28x-0%29\" Plug in \"m=-3%2F2\", \"x%5B1%5D=0\", and \"y%5B1%5D=-1\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y%2B1=%28-3%2F2%29%2Ax%2B%283%2F2%29%280%29\" Distribute \"-3%2F2\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y%2B1=%28-3%2F2%29%2Ax-0%2F2\" Multiply

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " \"y=%28-3%2F2%29%2Ax-0%2F2-1\"Subtract \"-1\" from both sides to isolate y
\n" ); document.write( "
\n" ); document.write( " \"y=%28-3%2F2%29%2Ax-0%2F2-2%2F2\" Make into equivalent fractions with equal denominators

\n" ); document.write( " \"y=%28-3%2F2%29%2Ax-1\" Reduce any fractions
