Best ResponseYou've already chosen the best response.1Well, to create linear function, you are going to need slope and yintercept, right?

Best ResponseYou've already chosen the best response.1So your goal is to track slope and yintercept.

Best ResponseYou've already chosen the best response.1Look at table. For each time x value increase by 1, how much do yvalue increase or decrease?

Best ResponseYou've already chosen the best response.1Close. decrease by 3. Or you can say increase by 3.

Best ResponseYou've already chosen the best response.1So use this fact, what is y when x=0?

Best ResponseYou've already chosen the best response.1So yintercept is 4. So your equation would looks like \(f(x) = mx4\)

Best ResponseYou've already chosen the best response.1we still don't know slope m But we can eliminate choices. We are down to either A or C.
