The parallel line has the same slope as 4/5 x-7. So the line is in the form $\"y=%284%2F5%29x%2Bb\"$ . Plugging in -20 for x and 7 for y, we get $\"7=%284%2F5%29%2A-20%2Bb\"$ . $\"7=-16%2Bb\"$ . $\"b=7%2B16=23\"$ . So the equation is $\"y=%284%2F5%29x%2B23\"$ .
$\"graph%28500%2C500%2C-20%2C20%2C-20%2C20%2Cy=%284%2F5%29x-7%2Cy=%284%2F5%29x%2B23%29\"$ . \n" ); document.write( "
