To find the unit rate for Fred’s Sub Shop, we need to find the slope of the line segment.
Using the coordinates given:
Slope = (Change in y) / (Change in x)
Slope = (30 - 0) / (6 - 0) = 30/6 = 5
This means that for every increase of 1 in the number of subs, the cost increases by $5.
Therefore, the unit rate for Fred’s Sub Shop is option B: $5 for 1 sub.
