Question

state whether each function is a linear function. write yes or no. explain.
xy = - 1

Answer 1

Answer:  It's not linear.

Step-by-step explanation: A linear function must have a degree of 0 or 1. This function equals to y= -1/x. -1/x has a degree of negative 1 since x^-1 =1/x. So this is not linear.
