m: -6, -12, -16

Which function rule would help you find the values in the table.

m = -3n

m = n - 6

m = n -3

m = -6n

**Steve**, Thursday, May 9, 2013 at 4:22pmWell, I'd say -3n, except that -3(6) = -18, not -16.

Typo?

As you can see, none of the choices fits all three pairs.

**Steve**, Thursday, May 9, 2013 at 4:28pmYou can see that the three points do not lie on a straight line, so no linear function will do. There is a parabola which contains all three points

m = (n^2-18n+8)/4

but that's not an option

unless the -16 is really -18

But, m = -3n is the closest of the three.

At least it contains two of the pairs; the other choices miss the mark for all three of them.

**Batman**, Thursday, May 9, 2013 at 4:33pmWAIT! It is -18 not -16. Sorry
