Algebra.Com's Answer #356847 by mathie123(224)![]() ![]() ![]() You can put this solution on YOUR website! 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( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \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( " \n" ); document.write( "Multiple every term by 3 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now multiply every term by 5 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \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( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hopefully this helps:) \r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
