The equation yˆ=3.07x+1.03 models the number of quarts of milk consumed in a household in a week, where x represents the number of children in the household. What does the y-intercept represent in the context of the situation?
-A household without children would consume about 3 quarts of milk in a week.
-A household without children would consume about 1 quart of milk in a week.
-A household with 1 child would consume about 3 quarts of milk in a week.
-A household with 1 child would consume about 1 quart of milk in a week.

The answer would be the second option, "A household without children would consume about 1 quart of milk in a week."
This is because the y-intercept is the y-value when x = 0. Plug in the value 0 for x and you get the y-intercept. If x is 0, then there are no kids, but y = 1.03, so 1.03 quarts of milk would be consumed if there were no children.
