The ordered pairs (-3, -11), (0, -2), (3, 7), and (6, 16) represent a function. What is the rule for this function?

a) y = x + 9
b) y = 2x + 4
c) y = x + 3
d) y = 3x - 2

pick two points and find the slope - $$y^2-y^1/x^2-x^2$$

@AihberKhan

aihberkhan · Answer

Okay so we have to start by picking two points. So lets use $(-3, -11)$ and $ (0, -2)$

aihberkhan · Answer

Now we have to use the equation that @RhondaSommer gave us and plug in the values.

aihberkhan · Answer

So when plugging it in we would get $(-2) - (-11)/0 - (-3)$

aihberkhan · Answer

So now when you solve you should get $3$

So I think the answer is D, but once again you may want to double check :)
