Find the slope by using this equation
\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=%280%29%2F%289%29\"
\n" ); document.write( "\"m=0\"
\n" ); document.write( "Plug in value of m into
\n" ); document.write( "\"y=mx%2Bb\"
\n" ); document.write( "\"y=0x%2Bb\"
\n" ); document.write( "Plug in any point, I'm selecting (-4,-10), into the equation
\n" ); document.write( "\"-10=0%2A%28-4%29%2Bb\" Since m=0, it becomes
\n" ); document.write( "\"-10=b\"
\n" ); document.write( "So the equation is
\n" ); document.write( "\"y=-10\"
\n" ); document.write( "
\n" );
