Determine if each function is linear or nonlinear.
a= linear b=non-linear

3x+y=12 a or b
y= \frac{6}{y} -2 a or b
y= \frac{x}{2} -3 a or b
y=3 x^{3} +5 a or b
y=x a or b

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
