Question

Write a rule for the function below x 2 4 6 y 8 6 4

Answer 1

Answer:

y= -1/2x+2

Step-by-step explanation: Our "y-intercept" (where x = 0) acts as the foundation of our function here.

We can extrapolate from what we have here...if x is 0, y is going to be 2.

So, we start at 2 for y, and every time we decrease x by 2, y increases by 1.

If we decrease x by just 1, y increases by ½.

This also goes in the opposite direction. Increase x by 1, decrease y by ½.

We can write the change in y as -½x.

That change is being added to our original value of 4, of course.

The equation of this line is .
