If inputs into production cannot be substituted for each other but have to be employed in fixed proportions isoquants are straight, downward-sloping lines. Indicate whether the statement is true or false ANSWER False. Isoquants are straight lines when inputs are perfect substitutes. When input relations are fixed they are right angles.
