Explanation:

The rate of change in a linear - relationship between total cost ($y$) and the number of pounds of grapes ($x$) represents the change in cost for each unit change in the number of pounds of grapes. Since the cost of the bread is a fixed amount (the $y$-intercept, which is $4$ when $x = 0$), the rate of change is due to the variable cost of the grapes.

each pound of grapes
