its in correct area
\n" ); document.write( "u need to know the point slope formula and slope intercept formula.
\n" ); document.write( "point slope is $\"m=%28y-y%29%2F%28x-x%29\"$
\n" ); document.write( "slope intercept $\"y=mx%2Bb\"$
\n" ); document.write( "(0,4)(7,-4)
\n" ); document.write( " $\"m=%284-%28-4%29%29%2F%280-7%29\"$
\n" ); document.write( " $\"m=%288%29%2F%28-7%29\"$
\n" ); document.write( " $\"m=-8%2F7\"$
\n" ); document.write( " $\"y=mx%2Bb\"$
\n" ); document.write( " $\"4=m%280%29%2Bb\"$
\n" ); document.write( " $\"4=b\"$
\n" ); document.write( " $\"y=%28-8%2F7%29x%2B4\"$ multiply by 7
\n" ); document.write( " $\"7y=-8x%2B28\"$
\n" ); document.write( " $\"7y%2B8x=28\"$ this is your line \n" ); document.write( "
