You can put this solution on YOUR website!

The easiest way to find this equation is to use point-slope form!
\r
\n" ); document.write( "\n" ); document.write( "First we need to find the slope:
\r
\n" ); document.write( "\n" ); document.write( "\"m=%28y2-y1%29%2F%28x2-x1%29\"
\r
\n" ); document.write( "\n" ); document.write( "\"m=%28-2-4%29%2F%288-4%29\"
\r
\n" ); document.write( "\n" ); document.write( "\"m=%28-6%29%2F4\"
\r
\n" ); document.write( "\n" ); document.write( "\"m=-3%2F2\"
\r
\n" ); document.write( "\n" ); document.write( "Then we can use the point-slope form: \"y-y1=m%28x-x1%29\"
\r
\n" ); document.write( "\n" ); document.write( "We will use the first point (4,4) and m=-3/2
\r
\n" ); document.write( "\n" ); document.write( "\"y-4=%28-3%2F2%29%2A%28x-4%29\"
\r
\n" ); document.write( "\n" ); document.write( "\"y=-3x%2F2%2B%284%2A3%29%2F2%2B4\"
\r
\n" ); document.write( "\n" ); document.write( "\"y=-3x%2F2%2B6%2B4\"
\r
\n" ); document.write( "\n" ); document.write( "\"y=-3x%2F2%2B10\"
\r
\n" ); document.write( "\n" ); document.write( "This is now in slope-intercept form, where we can easily see the slope is -3/2, and the y-intercept is (0,10).
\r
\n" ); document.write( "\n" ); document.write( "I hope this helps!
