Algebra.Com's Answer #373339 by Schaman_Dempster(26)![]() ![]() You can put this solution on YOUR website! Given equation of line is: 3x + 2y = 5 \n" ); document.write( "Let us transform this into slope intercept form: y = mx + b\r \n" ); document.write( "\n" ); document.write( "2y = 5 - 3x \n" ); document.write( "or y = -3x/2 + 5/2 \n" ); document.write( "Comparing it with slope-intercept form: y= mx + b \n" ); document.write( "Slope = m = -3/2\r \n" ); document.write( "\n" ); document.write( "If two lines are parallel, then they have equal slopes.\r \n" ); document.write( "\n" ); document.write( "So, the slope of the line parallel to 3x + 2y = 5 is -3/2 \n" ); document.write( "Using slope-intercept form, we can write the equation of a new line can be written as: \n" ); document.write( "y = mx + b \n" ); document.write( "y = -3x/2 + b\r \n" ); document.write( "\n" ); document.write( "Since this line also passes through (-2,-8) \n" ); document.write( "Therefore, \n" ); document.write( " -8 = (-3)*(-2)/2 + b \n" ); document.write( " -8 = 3 + b \n" ); document.write( " b = -8 -3 \n" ); document.write( " b = -11\r \n" ); document.write( "\n" ); document.write( "Hence the equation of the line parallel to 3x + 2y =5 is: \n" ); document.write( " y = -3x/2 - 11 \n" ); document.write( "or 2y = - 3x - 22 { Multiplying both the sides by 2} \n" ); document.write( "or 3x + 2y + 22 = 0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps~! \n" ); document.write( " |
