You can put this solution on YOUR website!
To find a perpendicular line, you need the opposite of the reciprocal.
\n" ); document.write( " $\"y=%28-3%2F4%29x%2B2\"$
\n" ); document.write( "The perpendicular line's slope would then be
\n" ); document.write( " $\"highlight%284%2F3%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your new line's slope intercept form:
\n" ); document.write( " $\"y=%284%2F3%29x%2Bb\"$
\n" ); document.write( "To find b, you need to use the given ordered pair.
\n" ); document.write( " $\"1=%284%2F3%29%2A%28-4%29%2Bb\"$
\n" ); document.write( " $\"1%2B%2816%2F3%29=b\"$
\n" ); document.write( " $\"highlight%2819%2F3=b%29\"$
\n" ); document.write( "Then put the numbers together\r
