Question

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

Answer 1

Answer 2

pick two points and find the slope - \[y^2-y^1/x^2-x^2\]

Answer 3

@AihberKhan

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

So now when you solve you should get \(3\)

Answer 8

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