First find the slope using the two points.
\n" ); document.write( "\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"
\n" ); document.write( "\"m=%28-8-%28-9%29%29%2F%28-6-%28-3%29%29\"
\n" ); document.write( "\"m=%28-8%2B9%29%2F%28-6%2B3%29\"
\n" ); document.write( "\"m=-1%2F3\"
\n" ); document.write( "The slope-intercept form of a line is
\n" ); document.write( "\"y=mx%2Bb\"
\n" ); document.write( "\"y=-%281%2F3%29x%2Bb\"
\n" ); document.write( "Use your points to determine b.
\n" ); document.write( "Using (-3,-9), you get
\n" ); document.write( "\"y=-%281%2F3%29x%2Bb\"
\n" ); document.write( "\"-9=-%281%2F3%29%28-3%29%2Bb\"
\n" ); document.write( "\"-9=1%2Bb\"
\n" ); document.write( "\"b=-10\"
\n" ); document.write( "\"y=-%281%2F3%29x-10\"
\n" ); document.write( "
\n" ); document.write( "
