You can put this solution on YOUR website!
First you need to find the slope so use \"m=%28y2-y1%29%2F%28x2-x1%29\"\r
\n" ); document.write( "\n" ); document.write( "Point 1 (3,-5) is x1 and y1
\n" ); document.write( "Point 2 (o,-9) is x2 and y2\r
\n" ); document.write( "\n" ); document.write( "solve
\n" ); document.write( "\"m=%28y2-y1%29%2F%28x2-x1%29\"
\n" ); document.write( "\"m=%28%28-9%29-%28-5%29%29%2F%280-3%29\"
\n" ); document.write( "\"m=%28-4%29%2F-3\" or \"4%2F3\" is your slope.\r
\n" ); document.write( "\n" ); document.write( "Next use point slope formula \"y-y1=m%28x-x1%29\" to find the equation.\r
\n" ); document.write( "\n" ); document.write( "\"y-%28-5%29=%284%2F3%29%28x-3%29\"<---- multiply using distributive property
\n" ); document.write( "\"y%2B5=%28%284%2F3%29%28x%29%29%28%284%2F3%29%28-3%29%29\"
\n" ); document.write( "\"y%2B5=%284%2F3%29x-4\"
\n" ); document.write( "\"y=%284%2F3%29x-9\" <----- your equation :)\r
\n" ); document.write( "\n" ); document.write( "
