I would be greatful if someone could show me how this is done, no matter how much I read and study, I still don't get it. Again Than-x and Have a Good Easter. \n" ); document.write( "
Algebra.Com's Answer #143184 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Use the equations of the lines to determine if they're parallel. y=0.15x+0.79, 0.11x-y=o.85. \n" ); document.write( "---------------- \n" ); document.write( "Find the slopes of the 2 lines by putting the eqns in the slope-intercept form, y = mx+b. m is the slope. \n" ); document.write( "----------------- \n" ); document.write( "All you have to do it solve for y. \n" ); document.write( "y=0.15x+0.79 eqn 1 \n" ); document.write( "0.11x-y=o.85 --> y = 0.11x - 0.85 eqn 2 \n" ); document.write( "m1 = 0.15 \n" ); document.write( "m2 = 0.11 \n" ); document.write( "The slopes are different, so they're not parallel.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
