Explanation:

The formula for kinetic friction force is \(F_{k}=\mu_{k}N\), where \(F_{k}\) is the kinetic friction force, \(\mu_{k}\) is the coefficient of kinetic friction, and \(N\) is the normal force. In a graph of \(F_{k}\) (y - axis) vs \(N\) (x - axis), the equation of the line is \(y = mx\) (since \(b = 0\) when there is no pre - existing friction force without a normal force). Comparing \(y=\mu_{k}x\) (where \(y = F_{k}\) and \(x = N\)) with \(y = mx\), we can see that the slope \(m=\mu_{k}\).

Answer:

coefficient; kinetic friction
