Let's look at the first part:
\n" ); document.write( "Determine the equation of the line which is parallel to the line 4x - 5y = 9\r
\n" ); document.write( "\n" ); document.write( "We know that parallel lines have the same slope (m value)
\n" ); document.write( "We can rearrange this formula into y=mx+b and find that m-value. \r
\n" ); document.write( "\n" ); document.write( "\"4x-5y=9\"
\n" ); document.write( "\"4x-5y%2B5y-9=9%2B5y-9\"
\n" ); document.write( "\"4x-9=5y\"
\n" ); document.write( "\"%284x-9%29%2F5=5y%2F5\"
\n" ); document.write( "\"%284x-9%29%2F5=y\"
\n" ); document.write( "\"y=%284%2F5%29%2Ax-9%2F5\"
\n" ); document.write( "So the m value is 4/5 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For the second part,
\n" ); document.write( "Again we can rearrange (2x) / 3 + (4y) / 5 = 8 into y=mx+b form and the b value will be the y-intercept \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282x%29+%2F+3+%2B+%284y%29+%2F+5+=+8\"
\n" ); document.write( "Multiple every term by 3
\n" ); document.write( "\"3%2A%28%282x%29+%2F+3%29+%2B+3%2A%28%284y%29+%2F+5%29+=+3%2A8\"
\n" ); document.write( "\"%282x%29+%2B+%28%2812y%29+%2F+5%29+=+24\"\r
\n" ); document.write( "\n" ); document.write( "Now multiply every term by 5
\n" ); document.write( "\"5%2A%282x%29+%2B+5%2A%28%2812y%29+%2F+5%29+=+5%2A24\"
\n" ); document.write( "\"%2810x%29+%2B+%2812y%29+=+120\"
\n" ); document.write( "\"%2810x%29+%2B+%2812y%29+-10x=+120-10x\"
\n" ); document.write( "\"12y=+120-10x\"
\n" ); document.write( "\"12y%2F12=+120%2F12-10x%2F12\"
\n" ); document.write( "\"y=+10-10%2F12%2Ax\"
\n" ); document.write( "\"y=-10%2F12%2Ax%2B10\"
\n" ); document.write( "From this we see that the b-value is 10\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the line we are looking for has the same slope and same y-intercept, we can plug these values right into the y-intercept form of a line (y=mx+b). This leaves:
\n" ); document.write( "\"y=4%2F5%2Ax%2B10\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hopefully this helps:) \r
