Find the slope:
\n" ); document.write( " $\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"$
\n" ); document.write( " $\"m=%28-10-%28-10%29%29%2F%285-%28-4%29%29\"$
\n" ); document.write( " $\"m=0%2F9\"$
\n" ); document.write( " $\"m=0\"$
\n" ); document.write( "Now plug in the slope into the general point slope equation. General point slope equation:
\n" ); document.write( " $\"y-y%5B1%5D=m%28x-x%5B1%5D%29\"$
\n" ); document.write( " $\"y-%28-10%29=0%2A%28x-5%29\"$ Plug in any point and the slope, lets use (5,-10) and m=-20/9
\n" ); document.write( " $\"y%2B10=0\"$ Solve for y
\n" ); document.write( " $\"y=-10\"$ \n" ); document.write( "

\n" );
