Step-by-step explanation:

A unit rate is basically which one increases more as time goes on. Now. to make it easier let me explain visual.

You have 50 apples at the start and every hour you get 200 more apples, sweet!

Now let's look at the chart.

The first one is 200x+100, this is wrong since this has a better start but you don't get as much apples.

Same goes for the B and C. The only one that would make sense is D since you're also adding 10 more apples for each one you increase.
