We first need to use the slope formula: \"%28y2-y1%29%2F%28x2-x1%29\"\r
\n" ); document.write( "\n" ); document.write( "Next we need to plug in our variables: \"%288-3%29%2F%282-1%29\"\r
\n" ); document.write( "\n" ); document.write( "That adds up to \"5%2F1\", or just 5.\r
\n" ); document.write( "\n" ); document.write( "Next we use the point slope form. \"y-y1=m%28x-x1%29\"
\n" ); document.write( "We can use either coordinate, so let's use the first one!\r
\n" ); document.write( "\n" ); document.write( "\"y-3=5%28x-1%29\"\r
\n" ); document.write( "\n" ); document.write( "Use the distributive property\r
\n" ); document.write( "\n" ); document.write( "\"y-3=5x-5\"\r
\n" ); document.write( "\n" ); document.write( "Add 3 to both sides:\r
\n" ); document.write( "\n" ); document.write( "\"y=5x-2\"\r
\n" ); document.write( "\n" ); document.write( "Final Answer: y=5x-2
\n" ); document.write( "
\n" );
