Find the slope using 13 for y2 and 7 for y1 , -5 for x2 and -2 for x1
\n" ); document.write( "\"+%28y2-y1%29%2F%28x2-x1%29+\"
\n" ); document.write( "\"+%2813-7%29%2F%28-5-%28-2%29%29+\"
\n" ); document.write( "\"+%2813-7%29%2F%28-5%2B2%29+\"
\n" ); document.write( "\"+6%2F%28-3%29+\"
\n" ); document.write( "-2
\n" ); document.write( "So the slope M is -2
\n" ); document.write( "Use y = Mx + b as a template and use -2 for M , -2 for x and 7 for y
\n" ); document.write( "from the point (-2,7)
\n" ); document.write( " \"7+=+%28-2%29%28-2%29+%2B+b+\"
\n" ); document.write( " 7 = 4 + b
\n" ); document.write( "add -4 to each side
\n" ); document.write( " 3 = b
\n" ); document.write( "We have slope M = -2 and b = 3 so our equation is
\n" ); document.write( "y = -2x + 3
\n" ); document.write( "
\n" );
