Question

Is the function described by the points in this table linear or nonlinear?

Answer 1

Answer: B. Linear

Step-by-step explanation: Y: -5, -1, 1, 3, 7

                                             X: -3, -1, 0, 1, 3

Ok, when you are doing a problem like this you are going to have to line you X and Y's up from least to greatest. Then, you will look at the X and see if any of the X values repeat. If any of your X values repeat, then they are "Non-Linear." If they do not repeat, then that means they are "Linear."
