Question

10 points 5) Which equation describes the function based on the data in the table below. *

Answer 1

Answer:

Option 4, y = $\frac{-1}{2}$x + 3

We can use the process of elimination with this problem;

     Right away I can tell that option 1 and option 3 are incorrect. Because we have the point (0, 3) the y-intercept will be + 3, option 2 and option 4 have this.

     Next, I can see that the y-values are going down, so the slope must be negative. This leaves me with option 4.

     I have also graphed a graph containing the points and option 4 so you can see it all lines up.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
