Linear function

Step-by-step explanation:

The equation would be y=0.20(x-1)+0.46 = 0.20x+0.26.

This comes from the fact that the first ounce, x=1, costs $0.46.  This means the extra $0.20 is not added when x=1.  

Each additional ounce costs $0.20; this is where the 0.20x in the equation comes from.

This equation is in the form y=mx+b, which means it is a linear function.

Additionally, we can tell it is linear because it has a constant rate of change (slope).
