Algebra.Com's Answer #154830 by Alan3354(69443) You can put this solution on YOUR website! Write downthe equations of the lines that are parallel to \n" ); document.write( "2y=5x+7, passing through (0,-3.5) \n" ); document.write( "--------------- \n" ); document.write( "There's only one. \n" ); document.write( "Find the slope, m, of the line by putting it in slope-intercept form (that means solve for y). \n" ); document.write( "2y=5x+7 \n" ); document.write( "y = (5/2)x + 7/2 \n" ); document.write( "m = 5/2 \n" ); document.write( "-------- \n" ); document.write( "All lines parallel have the same slope. \n" ); document.write( "Use \n" ); document.write( "y-y1 = m*(x-x1) where (x1,y1) is the point (0,-3.5) \n" ); document.write( "y+3.5 = (5/2)x \n" ); document.write( "2y+7 = 5x \n" ); document.write( "2y = 5x-7 \n" ); document.write( "or 5x-2y = 7 \n" ); document.write( " \n" ); document.write( " |
