This would be a slope. At some point of cost, no cereal would be present and all other costs would occur without anything in the packages.

You want COST per OUNCE, so cost is for the vertical component and ounce is for the horizontal component, so your slope is units of money per "weight". Actually dollars per ounce.

Points are (18, 3.60) and (12, 3.00). The equation for the line is not necessary. Just the slope is needed.
