Algebra.Com's Answer #82371 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! points ( 60, $1635) (120, $1770_ \n" ); document.write( "I got a slope of 2.25 \n" ); document.write( "That is correct: \n" ); document.write( "--------------------- \n" ); document.write( "My intercept is 1,500. \n" ); document.write( "Substitute into y = mx+b to solve for \"b\" \n" ); document.write( "1635 = 2.25*60 + b \n" ); document.write( "b = 1500 \n" ); document.write( "You are correct: \n" ); document.write( "--------------------- \n" ); document.write( " Not sure if this is right. Let x represent packages and y cost. What is the cost to send 200? What would my equation look like? \n" ); document.write( "EQUATION: \n" ); document.write( "y = 2.25x + 1500 \n" ); document.write( "To send 200 you get y = 2.25*200 + 1500 \n" ); document.write( "y = 450 +1500 \n" ); document.write( "y = 1950 \n" ); document.write( "=============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
