Explanation:

According to the formula for kinetic friction \(F_f=\mu_k F_N\), where \(F_f\) is the kinetic - friction force and \(F_N\) is the normal force. If we consider a graph of \(y = F_f\) (kinetic - friction force) versus \(x = F_N\) (normal force), the equation of the line is \(y=\mu_kx\). In the linear equation \(y = mx + b\) (where \(b = 0\) in this case), the slope \(m\) is equal to the coefficient of kinetic friction \(\mu_k\).

Answer:

coefficient, kinetic, friction
