Thread: So I kind of forgot how to do this over the summer!

Ok! I should know how to do this, but:


1. Complete the table and write a rule relating x and y (an eqaution)

X 3 ,-1, 0, 2, -5, -2, 1
Y 0,,,,,,,,,,-1 ,,,,,,,,,,-2


Sorry I do not know how to make tables on here! The blank spaces is where you complete the table. I tried making an equation.

Can I guess that this is supposed to be a linear function?

My first comment is that you ought to arrange the x's in either ascending or descending order:
x -2, -1, 0, 1, 2, 3
y,,,,,,,,,,,,,,-2, -1, 0

Now the pattern looks a lot clearer:




So each of these has a common value for , that is .

So let


Then


That looks like it fits what you've got in your table.
