A market supply curve has three prices - $400, $4.50 and $5.00 - with a quantity supplied of 7 tonnes at the price of $4.00.9 tonnes at $450 and 11 tonnes at $5.00 a: Is this supply curve a straightine? This curve is not a straight line because it does not have a constant slope. This curveis a straight line because it has a constant slope of 25 This curve is a straight line because it has a constant slope of 0.5 This curve is a straight line because it has a constant slope of What is the price elasticity of supply between pages 500 and $450 ang between prices $450 and 155.002Do not round your en tant to using the dutie door can your calculation de chat etter scias end door de The price oloticity of supply between price 54.0 and $450, and between prices $450 and $5.00 c.
