which of the following rules represents the function graphed?

a) f(x)=1/2x

b) f(x)=x

c) f(x)=x+2

B

Step-by-step explanation:

To figure out equation of a line, we need two points.

If you look at the graph, one point is and another point let's take .

The equation of the line is given by  

Where m is the slope with formula   and    is point 1 and    is point 2.

Solving for m, we have:

Thus we have  

To solve for c [the y-intercept] we plug in any point into x and y of this equation. Let's use the point . We have:

Thus we can write    or simply  

In function notation, we replace with

So we have

Answer choice B is right.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

i got 10.28 but that rounds up to 10.3
