Algebra.Com's Answer #184173 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! I need help figuring out this equation and I also need to graph it. Can you please help? 2(y+3)<4x. Thank you. \n" ); document.write( "------------------- \n" ); document.write( "You have an inequality in 2 variables. You can solve for x in terms of y, or for y in terms of x, but that's all \n" ); document.write( "-------------- \n" ); document.write( "To graph it, solve for y in terms of x: \n" ); document.write( "2(y+3)<4x Divide by 2 \n" ); document.write( "y+3<2x Subtract 3 \n" ); document.write( "y<2x-3 \n" ); document.write( "------- \n" ); document.write( "This is a linear function, so the graph will be a straight line. 2 points is sufficient to plot a straight line. \n" ); document.write( "--------- \n" ); document.write( "Use = instead of < to find 2 points. \n" ); document.write( "x...y \n" ); document.write( "0...-3 --> (0,-3) \n" ); document.write( "2...+1 --> (2,1) \n" ); document.write( "------------------ \n" ); document.write( "Plot those 2 points and draw a line thru them. The line is where y = 2x-3. \n" ); document.write( "The area below the line is where it's less than (<), not including the line.\r \n" ); document.write( "\n" ); document.write( "You can dl FREE software to make graphs at \n" ); document.write( "http://www.padowan.dk.com\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
