linear makes a stright line non linerar is not a stright line qudraite-variuable to the seccond power qubic-third power exponential-is a variuable inverse is when y is the variuable

on a graph a linear function must be stright, on a table it had to be a constant rate of change, equation- y=mx+b or ax+by=c
