Answer:
A, the weight of the new bar of a soap is 123 grams.
Step-by-step explanation:
In this instance, the y-intercept is at y = 123, where x = 0. Since x = 0, and 'x' represents the # of times the soap bar was used, this would mean that the bar has not been used at all.
Thus, a soap bar not used is a new bar of soap. Since the y-intercept represents this, it shows that a new bar of soap is 123 grams.
