The isoquant for Q=2 will be twice as far away from the origin in both directions compared to the isoquant for Q=1 and is a reflection of the fact that twice the amount of capital and labor are needed to produce twice the output.
As we move along an isoquant, we substitute capital for labor while maintaining the same output level. The amount of additional capital needed to compensate for a given decrease in labor (MRTS) increases as we also move further towards the capital-intensive end of the isoquant.
This property arises from the diminishing MRTS and as we move further towards either axis, we need increasingly more of the other factor to maintain the same output, causing the isoquant to bend inwards.
Isoquants for higher output levels (e.g., Q=2) are further away from the origin than those for lower output levels (e.g., Q=1). This is because more capital and labor are required to achieve higher production.
The isoquant for Q=1 will intersect the K-axis at a point where K=1 and L=0, and the L-axis at a point where K=0 and L=1 and follows from the equation above. In the same way, the isoquant for Q=2 will intersect the axes at points where K=4 and L=0, and K=0 and L=4, respectively.
