Two quantities x and y show a power curve relation y = 2.1x^1.7. Using base-10 logarithmic scales for both x and y axes, the curve is transformed to a line. Find the slope of the line. A) 2.1 B) 0.32 C) 1.7 D) 0.23

Question

Quizplus · Accepted Answer

The slope of the line in a log-log plot for a power curve relation $y = ax^b$ is equal to the exponent $b$. Here, the power curve relation is $y = 2.1x^{1.7}$, so the slope of the line on a log-log plot is $1.7$.
