Algebra.Com's Answer #143172 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! given point and parallel. (4,9) x+4y=5 \n" ); document.write( "----------------- \n" ); document.write( "Find the slope of the line. To find the slope, m, put it into slope-intercept form, y = mx + b. That means solve for y. \n" ); document.write( "x+4y=5 \n" ); document.write( "4y = -x + 5 \n" ); document.write( "y = (-1/4)x + 5/4 \n" ); document.write( "m = -1/4 \n" ); document.write( "All lines parallel to this one will have the same slope. \n" ); document.write( "--------------- \n" ); document.write( "then use \n" ); document.write( "y-y1 = m*(x-x1) where (x1,y1) is the point. \n" ); document.write( "y-9 = (-1/4)*(x-4) \n" ); document.write( "y-9 = (-1/4)x + 1 \n" ); document.write( "y = (-1/4)x + 10 slope-intercept form \n" ); document.write( "x + 4y = 40 standard form\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
