note that as x grows by 1, y goes down by 5. So, the slope is -5, and your first guess is
y = -5x
But, it has to be adjusted, since y(0) is not 0...
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
Find the function rule.
[x| -2| -1| 0| 1| 2]
[y| 9| 4| -1| -6| -11]
PLEASE HELP!!!

Wait don't understand can you explain to be better.
Read about the slope-intercept form of a line
If y changes by a constant amount as x changes, then that gives you teh slope (m) of the line. Then the equation is
y = mx+b
For this relation, m = -5
Now you just have to find b, the y-intercept. Set x=0 and find y.
If this makes no sense, you clearly have not paid attention in class, nor studied your text.
