8Equations: Linear or Nonlinear REMEMBER: x1 = x and x0 = 1In “y = ” form, is x raised to a power of 1 or 0?Does x appear in the numerator?y = 6/xy = x3 + 1y = x + 4nonlineary = ½ xnonlineary = 4linearlinearlinear
10Pointers to Keep in Mind A table is linear if the rate of change is constant.There is a common difference.A graph is linear if it is a straight line.An equation is linear if the power of x is either 1 or 0 and it appears in the numerator.
